This document proposes a remote sensing image fusion approach that combines the Brovey transform and wavelet transforms. The Brovey transform is used first to reduce spectral distortion, followed by a wavelet transform to reduce spatial distortion. The approach was tested on MODIS and SPOT data as well as ETM+ and SPOT data. Statistical analysis showed the proposed technique performed better than traditional fusion techniques like IHS, PCA, and the Brovey transform alone in terms of metrics like correlation coefficient, entropy, and structural similarity. Future work will focus on improving the technique and applying fused images to classification tasks.

Pan sharpening
Pan sharpening is a process that merges high-resolution panchromatic imagery with lower-resolution multispectral imagery to create a single high-resolution color image. It provides the best of both types of imagery - high spectral resolution and high spatial resolution. There are several common pan sharpening methods including Brovey, IHS, Esri, simple mean, and Gram-Schmidt transformations. Landsat 8 imagery for example consists of bands with 30m resolution except for the panchromatic band which has 15m resolution, and pan sharpening can be applied in GIS software like ArcGIS to improve the resolution of the multispectral bands.
IMAGE FUSION IN IMAGE PROCESSING
This document discusses image fusion techniques at different levels of abstraction: pixel level, feature level, and decision level. It describes various fusion methods including numerical (e.g. multiplicative, Brovey), color related (e.g. IHS), statistical (e.g. PCA, Gram Schmidt), and feature level (e.g. Ehlers) techniques. Both qualitative (visual) and quantitative (statistical measures like RMSE, correlation coefficient, entropy) methods to assess fusion quality are outlined. Image fusion has applications in improving classification and displaying sharper resolution images.
Image Fusion
This document describes a method for pixel-level image fusion using principal component analysis (PCA). PCA is used to transform correlated image pixels into a set of uncorrelated principal components. The first principal component accounts for the most variance in the pixel values. To fuse images, the pixels of the input images are arranged into vectors and subtracted from their mean. PCA is applied to get the eigenvectors corresponding to the largest eigenvalues. The normalized eigenvectors are used to compute a fused image as a weighted sum of the input images. Performance is evaluated using metrics like standard deviation, entropy, cross-entropy, and fusion mutual information, with higher values of these metrics indicating better quality of the fused image.
A review of change detection techniques
The document summarizes seven categories of change detection techniques:
1. Algebra based approaches include image differencing, regression, ratioing, and change vector analysis. These methods are simple to implement but cannot provide complete change matrices.
2. Transformation techniques apply transformations like PCA and tasseled cap to images before change detection.
3. Classification based techniques perform post-classification comparison or combine classification with other algorithms.
4. Advanced models use techniques like spectral mixture analysis and biophysical parameters.
5. GIS and remote sensing are integrated in some methods.
6. Visual analysis relies on human interpretation of image differences.
7. Other techniques include measures of spatial dependence,
Image quality assessment and statistical evaluation
This document discusses image quality assessment and statistical evaluation of remote sensing data. It explains that remote sensing data can contain errors introduced by the environment, sensor issues, or processing errors. Assessing image quality and statistical characteristics is important and can be done by examining histograms, pixel values, and univariate and multivariate statistics to identify anomalies or redundancy in the data. The document also provides mathematical notation for describing remote sensing data and discusses concepts like populations, samples, sampling error, and the importance of metadata for image analysis.
Accuracy assessment of Remote Sensing Data
Accuracy assessment is an essential step in any remote sensing classification. It involves collecting reference data through methods like GPS ground sampling and comparing the classifications to determine accuracy. Key aspects of accuracy assessment include error matrices to calculate overall, user's, and producer's accuracies. User's accuracy indicates errors of commission while producer's accuracy reflects errors of omission. ERDAS Imagine software can be used to import reference data and generate accuracy reports to evaluate classification performance.
Hit and-miss transform
The hit-and-miss transform is a binary morphological operation that can detect particular patterns in an image. It uses a structuring element containing foreground and background pixels to search an image. If the structuring element pattern matches the image pixels underneath, the output pixel is set to foreground, otherwise it is set to background. The hit-and-miss transform can find features like corners, endpoints, and junctions and is used to implement other morphological operations like thinning and thickening. It is performed by matching the structuring element at all points in the image.
Object Based Image Analysis
- The document discusses object-based image analysis (OBIA) and its advantages over traditional pixel-based image analysis for extracting information from remote sensing imagery.
- OBIA involves segmenting images into image objects based on characteristics like color, shape, texture, and relationships between objects. These objects can then be classified thematically.
- Several software packages that perform OBIA are discussed, including eCognition, IDRISI, ENVI, and MadCat. Key steps in the OBIA process like segmentation, classification rule development, and accuracy assessment are also outlined.
- An example of using OBIA to extract water features from a high resolution image is provided to illustrate the technique.

Application of GIS in Mine Contamination and Associated Environmental Impacts
This document discusses the application of GIS and remote sensing methods to measure environmental impacts from mining contamination. It outlines two case studies where GIS was used: 1) A study in Turkey that generated DEM and flow accumulation maps from ASTER satellite imagery to identify trace element contamination patterns from an abandoned coal mine. Higher concentrations were found along flow pathways downstream from contamination sources. 2) A study with the Navajo tribe that created water hauling and soil restriction maps using GIS to develop an effective risk communication strategy about uranium exposures from abandoned mines. The maps aided risk understanding but language barriers remained a limitation. In conclusion, remote sensing and GIS provide low-cost alternatives for mapping contamination to inform remediation efforts.
Wavelet based image fusion
This document discusses wavelet-based image fusion techniques. Image fusion combines information from multiple images of the same scene to create a fused image that is more informative than any single input image. The wavelet transform decomposes images into different frequency bands, and image fusion algorithms merge the corresponding bands from input images. Common fusion rules include choosing the maximum, minimum, mean, or a value from one image at each band location. The inverse wavelet transform then reconstructs the fused image. Wavelet-based fusion can integrate high spatial and high spectral information from images like panchromatic and multispectral satellite data.
06 spatial filtering DIP
Spatial filtering involves applying filters or kernels to images to enhance or modify pixel values based on neighboring pixel values. Linear spatial filtering involves taking a weighted sum of pixel values within the filter window. Common filters include averaging filters for noise reduction, median filters to reduce impulse noise while preserving edges, and sharpening filters like Laplacian filters and unsharp masking to enhance details.

Spatial enhancement
This document discusses methods for enhancing spatial features in images. It describes spatial filtering and convolution, which involve applying kernels or filters to images to emphasize different spatial frequencies. Low-pass filters smooth images by reducing high spatial frequencies related to fine detail, while high-pass filters have the opposite effect of sharpening images. Edge enhancement filters aim to highlight linear features by increasing contrast around edges. Fourier analysis represents images as combinations of sine and cosine waves of different frequencies and can reveal features aligned in various directions.
Digital image classification22oct
Digital image classification is the process of sorting pixels into categories based on their spectral values. There are supervised and unsupervised classification methods. Supervised classification involves using training sites of known categories to define statistical signatures for each class. Unsupervised classification groups pixels into clusters without prior class definitions. Validation is needed to assess classification accuracy by comparing results to ground truth data. Factors like training site selection and signature separability impact classification performance.
Accuracy Assessment in Remote Sensing
Accuracy assessment is an important part of any classification project. It compares the classified image to another data source that is considered being accurate or ground truth data.

fuzzy image processing
Fuzzy image processing uses fuzzy logic techniques to process digital images. It can handle vagueness and ambiguity in images. The main steps are image fuzzification, modifying membership values, and image defuzzification. Fuzzy image processing has applications in noise removal, edge detection, segmentation, and contrast enhancement. It provides advantages over traditional techniques by allowing for graded membership in sets rather than binary membership.
GNSS(GLOBAL NAVIGATION SATELLITE SYSTEM)
Global Navigation Satellite Systems (GNSS) allow users to pinpoint their geographic location anywhere in the world using signals from satellites. The two main GNSS currently in operation are the United States' Global Positioning System (GPS) and Russia's Global Navigation Satellite System (GLONASS). There are also other regional GNSS including the European Union's Galileo, China's BeiDou, Japan's QZSS, and India's NavIC. GPS and GLONASS both provide positioning and timing data to users worldwide, with GPS generally offering higher accuracy overall and GLONASS performing better at high latitudes.
Image classification
This document discusses supervised image classification using support vector machines (SVM). It begins with an abstract and introduction on image classification and supervised classification. It then discusses the methodology, including pre-processing, segmentation, feature extraction, and classification steps. SVM classification involves extracting pixels from images into a data frame, using random pixels for training and the rest for testing. The SVM classifier is created using the training set and histograms. Accuracy is measured using precision formulas. Implementing the process with horse images achieved up to 90% accuracy when retraining with additional images.

Resampling- GIS
Resampling is defined as deriving pixel values for a new image from an existing image. There are two main types of resampling: nearest neighbor and bilinear interpolation. Nearest neighbor assigns the value of the nearest pixel in the input image to pixels in the output image, producing blocky results best used for discrete data. Bilinear interpolation takes the weighted average of the nearest four pixels, producing smoother results best used for continuous data. Cubic convolution is similar but uses sixteen nearest pixels, providing the sharpest results but longest processing time and is best for continuous data.

1) The document compares an approximate representation to a linguistic representation in Fuzzy-UCS, a Michigan-style learning fuzzy classifier system that originally used linguistic rules.
2) An approximate representation allows each variable to define its own fuzzy set rather than sharing semantics through linguistic terms. This aims to gain expressivity over the linguistic approach.
3) An experiment compares the approximate Fuzzy-UCS to linguistic Fuzzy-UCS and a baseline C4.5 classifier on 20 real-world problems, evaluating training accuracy, test accuracy, and rule set size. The approximate approach fits training data better but does not clearly outperform linguistic Fuzzy-UCS on test data, possibly due to overfitting on some
IWLCS'2007: Fuzzy-UCS: Preliminary Results
1. Fuzzy-UCS is a proposed fuzzy rule-based Michigan-style learning classifier system that uses linguistic fuzzy rules for supervised learning. It is derived from UCS by introducing a fuzzy linguistic rule representation and modifying operators that deal with rules.
2. The goal is to achieve similar performance to UCS but with more interpretable fuzzy rules and a lower number of rules.
3. Fuzzy-UCS uses linguistic fuzzy rules of the form "IF x1 is A1 and x2 is A2 ... and xn is An THEN class" where the variables are fuzzy terms rather than interval ranges. This provides a robust way to handle noisy, imprecise and incomplete data.

SINGLE IMAGE SUPER RESOLUTION: A COMPARATIVE STUDY
The majority of applications requiring high resolution images to derive and analyze data
accurately and easily. Image super resolution is playing an effective role in those applications.
Image super resolution is the process of producing high resolution image from low resolution
image. In this paper, we study various image super resolution techniques with respect to the
quality of results and processing time. This comparative study introduces a comparison between
four algorithms of single image super-resolution. For fair comparison, the compared algorithms
are tested on the same dataset and same platform to show the major advantages of one over the
others.

The document compares three image fusion techniques: wavelet transform, IHS (Intensity-Hue-Saturation), and PCA (Principal Component Analysis). For each technique, it describes the methodology, syntax used, and features. It then applies each technique to sample images to produce fused images. The RGB values of the fused images are recorded and compared in a table. The wavelet technique uses max area selection and consistency verification for feature selection. IHS transforms RGB to IHS values and replaces intensity with a panchromatic image. PCA replaces the first principal component with a high-resolution panchromatic image. The document concludes no single technique is best and the quality depends on the application.
An Improved Image Fusion Scheme Based on Markov Random Fields with Image Enha...
Image fusion is an important field in many image processing and analysis tasks in which fusion image data are acquired
from multiple sources. In this paper, we investigate the Image fusion of remote sensing images which are highly corrupted by salt and
pepper noise. In our paper we propose an image fusion technique based Markov Random Field (MRF). MRF models are powerful
tools to analyze image characteristics accurately and have been successfully applied to a large number of image processing
applications like image segmentation, image restoration and enhancement, etc.,. To de-noise the corrupted image we propose a
Decision based algorithm (DBA). DBA is a recent powerful algorithm to remove high-density Salt and Pepper noise using sheer
sorting method is proposed. Previously many techniques have been proposed to image fusion. In this paper experimental results are
shown our proposed Image fusion algorithm gives better performance than previous techniques.
PAN Sharpening of Remotely Sensed Images using Undecimated Multiresolution De...
ABSTRACT : In many applications satellite images are used on the basis of resolution, where a high resolution is one of the major issues in the remotely sensed image. In this paper, we propose a new pan-sharpening technique to enhance the resolution of the satellite image by injecting the high frequency details from High-Resolution Panchromatic (HRP) image into Low Resolution Multi-Spectral (LRMS) image using Discrete Wavelet Transform (DWT) and Stationary Wavelet Transform (SWT). SWT algorithm is designed in such a way to overcome the lack of translation-invariance of DWT and is used to enhance the edges on the intermediate stage by preserving spatial information. Translation-invariance is attained by eliminating the down samplers and up samplers present in the DWT. Results show that the performance of the proposed fusion method is better than that of the state-of-art methods in terms of visual quality and other several frequently used metrics, such as the Correlation Coefficient, Peak Signal to Noise Ratio and Root Mean Square Error. Keywords: Image Fusion, Pan-sharpening, Discrete Wavelet Transform, Stationary Wavelet Transform, Quality Metrics

The document describes a method for image fusion and optimization using stationary wavelet transform and particle swarm optimization. It summarizes that image fusion combines information from multiple images to extract relevant information. The proposed method uses stationary wavelet transform for image decomposition and particle swarm optimization to optimize the fused results. It applies stationary wavelet transform to source images to decompose them into wavelet coefficients. Particle swarm optimization is then used to optimize the transformed images. The inverse stationary wavelet transform is applied to the optimized coefficients to generate the fused image. The method is tested on various images and performance is evaluated using metrics like peak signal-to-noise ratio, entropy, mean square error and standard deviation.

Image Compression using Hybrid Slant Wavelet where Slant is Base Transform and Sinusoidal Transforms are Local Transforms
Kurmi 2015-ijca-905317
The document describes an image fusion approach that uses adaptive fuzzy logic modeling for global processing followed by Markov random field modeling for local processing.
It begins by introducing image fusion and its applications. It then discusses existing fusion approaches and their limitations. The proposed approach first uses an adaptive fuzzy logic model to minimize redundant information globally. It then applies Markov random field modeling locally for fusion. Experimental results showed the proposed approach improved the universal image quality index by 30-35% compared to fusion with Markov random field modeling alone.

This document summarizes a study that proposed an enhancement technique for the iterative back projection (IBP) super resolution estimation method. The study aimed to improve the IBP method by using a Lorentzian error function with a sharp infinite symmetrical filter (SISEF) to provide edge enhancement. The IBP method suffers from jaggy and ringing artifacts due to the iterative reconstruction process and lack of edge guidance during back projection. The proposed method combines IBP with the Lorentzian SISEF filter to produce a higher resolution output image with finer edge details while increasing robustness to noise and reducing ringing artifacts. The SISEF filter provides precise edge information to guide the back projection process, and the Lorentzian error norm suppresses
A Review of Image Contrast Enhancement Techniques

Finally, the conclusion is that contrast enhancement using digital image processing continues to be an active area of research that can help solve problems across many fields involving image analysis.
PCA & CS based fusion for Medical Image Fusion
Compressive sampling (CS), also called Compressed sensing, has generated a tremendous amount of excitement in the image processing community. It provides an alternative to Shannon/ Nyquist sampling when the signal under acquisition is known to be sparse or compressible. In this paper, we propose a new efficient image fusion method for compressed sensing imaging. In this method, we calculate the two dimensional discrete cosine transform of multiple input images, these achieved measurements are multiplied with sampling filter, so compressed images are obtained. we take inverse discrete cosine transform of them. Finally, fused image achieves from these results by using PCA fusion method. This approach also is implemented for multi-focus and noisy images. Simulation results show that our method provides promising fusion performance in both visual comparison and comparison using objective measures. Moreover, because this method does not need to recovery process the computational time is decreased very much.

Super-resolution (SR) is the process of obtaining a high resolution (HR) image or
a sequence of HR images from a set of low resolution (LR) observations. The block
matching algorithms used for motion estimation to obtain motion vectors between the
frames in Super-resolution. The implementation and comparison of two different types of
block matching algorithms viz. Exhaustive Search (ES) and Spiral Search (SS) are
discussed. Advantages of each algorithm are given in terms of motion estimation
computational complexity and Peak Signal to Noise Ratio (PSNR). The Spiral Search
algorithm achieves PSNR close to that of Exhaustive Search at less computation time than
that of Exhaustive Search. The algorithms that are evaluated in this paper are widely used
in video super-resolution and also have been used in implementing various video standards
like H.263, MPEG4, H.264.

INFORMATION SATURATION IN MULTISPECTRAL PIXEL LEVEL IMAGE FUSION
The availability of imaging sensors operating in multiple spectral bands has led to the requirement of
image fusion algorithms that would combine the image from these sensors in an efficient way to give an
image that is more informative as well as perceptible to human eye. Multispectral image fusion is the
process of combining images from different spectral bands that are optically acquired. In this paper, we
used a pixel-level image fusion based on principal component analysis that combines satellite images of the
same scene from seven different spectral bands. The purpose of using principal component analysis
technique is that it is best method for Grayscale image fusion and gives better results. The main aim of
PCA technique is to reduce a large set of variables into a small set which still contains most of the
information that was present in the large set. The paper compares different parameters namely, entropy,
standard deviation, correlation coefficient etc. for different number of images fused from two to seven.
Finally, the paper shows that the information content in an image gets saturated after fusing four images.
A comparative study for the assessment of Ikonos satellite image-fusion techn...
Image-fusion provide users with detailed information about the urban and rural environment, which is useful for applications such as urban planning and management when higher spatial resolution images are not available. There are different image fusion methods. This paper implements, evaluates, and compares six satellite image-fusion methods, namely wavelet 2D-M transform, gram schmidt, high-frequency modulation, high pass filter (HPF) transform, simple mean value, and PCA. An Ikonos image (PanchromaticPAN and multispectral-MULTI) showing the northwest of Bogotá (Colombia) is used to generate six fused images: MULTIWavelet 2D-M, MULTIG-S, MULTIMHF, MULTIHPF, MULTISMV, and MULTIPCA. In order to assess the efficiency of the six image-fusion methods, the resulting images were evaluated in terms of both spatial quality and spectral quality. To this end, four metrics were applied, namely the correlation index, erreur relative globale adimensionnelle de synthese (ERGAS), relative average spectral error (RASE) and the Q index. The best results were obtained for the MULTISMV image, which exhibited spectral correlation higher than 0.85, a Q index of 0.84, and the highest scores in spectral assessment according to ERGAS and RASE, 4.36% and 17.39% respectively.

It applies these techniques to fuse a high-resolution panchromatic Ikonos image with a lower-resolution multispectral Ikonos image of an area near Bogota, Colombia. It then evaluates the spatial and spectral quality of the resulting fused images using four metrics: correlation coefficient, erreur relative globale adimensionnelle de synthese (ERGAS), relative average spectral error (RASE), and the Q index. The technique producing the best results was found to be the simple mean value fusion,

QUALITY ASSESSMENT OF PIXEL-LEVEL IMAGE FUSION USING FUZZY LOGIC
Image fusion is to reduce uncertainty and minimize redundancy in the output while maximizing relevant information from two or more images of a scene into a single composite image that is more informative and is more suitable for visual perception or processing tasks like medical imaging, remote sensing, concealed weapon detection, weather forecasting, biometrics etc. Image fusion combines registered images to
produce a high quality fused image with spatial and spectral information. The fused image with more information will improve the performance of image analysis algorithms used in different applications. In this paper, we proposed a fuzzy logic method to fuse images from different sensors, in order to enhance the
quality and compared proposed method with two other methods i.e. image fusion using wavelet transform and weighted average discrete wavelet transform based image fusion using genetic algorithm (here onwards abbreviated as GA) along with quality evaluation parameters image quality index (IQI), mutual
information measure ( MIM), root mean square error (RMSE), peak signal to noise ratio (PSNR), fusion factor (FF), fusion symmetry (FS) and fusion index (FI) and entropy. The results obtained from proposed fuzzy based image fusion approach improves quality of fused image as compared to earlier reported
methods, wavelet transform based image fusion and weighted average discrete wavelet transform based
image fusion using genetic algorithm.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

- 3. Overview Introduction The Objective The Brovey Transform The Wavelet Transform The Proposed Image Fusion Approach Experimental Results Conclusion And Future Work
- 4. Introduction Remote sensing has a huge amount of data different spatial resolution for panchromatic and multispectral imagery For the optimum benefit of these characteristics. It should be collected in a single image. There is no single system offers spatial or multispectral resolution at the same time.
- 5. Introduction Image fusion is used to combine multi-image information in one image which is more suitable to human vision or more adapt to further image processing analysis. Recently, image fusion has become one of the focuses in image processing field
- 6. The Objective Introduces a remote sensing image fusion approach based on a modified version of the Brovey transform and wavelets to reduce the spectral distortion in the Brovey transform and spatial distortion in the wavelet transform.
- 7. The Brovey Transform The basic procedure of the Brovey Transform first multiplies each MS band by the high-resolution Pan band, and then divides each product by the sum of the MS bands.
- 8. The Wavelet Transform wavelet image fusion decomposed the two input images separately into approximate coefficients and detailed coefficients. high detailed coefficients of the multi-spectral image are replaced with those of the pan image. The new wavelet coefficients of the multi-spectral image are transformed with the inverse wavelet transform to obtain the fusion multi-spectral image
- 9. The Proposed Image Fusion Approach Preprocessing stage Registration Upsampling Histogram matching Image fusion stage
- 10. The Proposed Image Fusion Approach Fusion Algorithm 1: Apply the Brovey transform on the multispectral images (R, G, and B) and the panchromatic image and produce new images (Rnew, Gnew and Bnew). 2: Decompose the high resolution image (i.e. Pan image) into into a set of low resolution with the wavelet transform. 3: The wavelet transform with the same decomposition scale is applied to obtain the Wavelet coefficients of the new image (Rnew, Gnew and Bnew). 4: Replace a low frequency of Pan image with low frequency of MS band at the level. 5:The Proposed wavelet coefficients fusion scheme is carried to reconstruct new image’s wavelet coefficients. 6: The reconstruct image wavelet coefficients. 7: The last output image is generated by applying inverse wavelet transform (IWT) with reconstructed wavelet coefficients.

- 16. Conclusion and Future works The traditional image fusion techniques have limitation and do not meet the needs of remote sensing Therefore our way is the only hybrid systems. Hybrid techniques in pixel level are more efficiency technique than traditional techniques. The proposed image fusion technique has achieved good results and we will be in the future work on improving it. In the future work we will use fused images for the classification and study of the concerned area.
