A new approach of edge detection in sar images using region based active cont...eSAT Journals
Abstract This paper presents a new methodology for the edge detection of complex radar images. The approach includes the edge improvisation algorithm and followed with edge detection. The nature of complex radar images made edge enhancement part before the edge detection as the data is highly heterogeneous in nature. Thus, the use of discrete wavelet transform in the edge improvisation algorithm is justified. Then region based active contour model is used as edge detection algorithm. The paper proposes the distribution fitting energy with a level set function and neighborhood means and variances as variables. The performance is tested by applying it on different images and the results are been analyzed. Keywords: Edge detection, Edge improvisation, Synthetic Aperture radar (SAR), wavelet transforms.
This document presents a methodology for land use mapping using segmentation techniques on coarse resolution SAR data. It explores extracting urban extents using the BuiltArea algorithm, then segmenting the SAR images using different algorithms like Canny edge detection. Land use classes like commercial, residential and green areas are classified after feature selection and majority rule application. Testing on Shanghai showed potential for moderate SAR in urban monitoring. Preliminary fusion with optical data from Beijing-1 satellite improved segmentation accuracy and classification results. Future work will explore polarimetric features and additional classes with multitemporal SAR segmentation approaches.

AN EFFICIENT SYSTEM FOR FORWARD COLLISION AVOIDANCE USING LOW COST CAMERA & E...aciijournal
Forward Collision Avoidance (FCA) systems in automobiles is an essential part of Advanced Driver Assistance System (ADAS) and autonomous vehicles. These devices currently use, radars as the main sensor. The increasing resolution of camera sensors, processing capability of hardware chipsets and advances in image processing algorithms, have been pushing the camera based features recently. Monocular cameras face the challenge of accurate scale estimation which limits it use as a stand-alone sensor for this application. This paper proposes an efficient system which can perform multi scale object
detection which is being patent granted and efficient 3D reconstruction using structure from motion (SFM)
framework. While the algorithms need to be accurate it also needs to operate real time in low cost
embedded hardware. The focus of the paper is to discuss how the proposed algorithms are designed in such
a way that it can be provide real time performance on low cost embedded CPU’s which makes use of only Digital Signal processors (DSP) and vector processing cores.

This document summarizes a research paper that proposes a new method for detecting digital image forgeries by analyzing inconsistencies in the color of illumination across image regions. Existing illumination-based forgery detection methods have limitations like requiring manual interaction or not handling specular regions well. The proposed method extracts texture and edge-based features from illuminant estimates of similar image regions using physics and statistics-based models.

Hardware Unit for Edge Detection with Comparative Analysis of Different Edge ...paperpublications3
Abstract: An edge in an image is a contour across which the brightness of the image changes abruptly. In image processing, an edge is often interpreted as one class of singularities. Edge detection is an important task in image processing. It is a main tool in pattern recognition, image segmentation, and scene analysis. An edge detector is basically a high pass filter that can be applied to extract the edge points in an image. This topic has attracted many researchers and many achievements have been made. Many researchers provided different approaches based on mathematical calculations which some of them are either robust or cost effective. A new algorithm will be proposed to detect the edges of image with increased robustness and throughput. Using this algorithm we will reduce the time complexity problem which is faced by previous algorithm. We will also propose hardware unit for proposed algorithm which will reduce the area, power and speed problem. We will compare our proposed algorithm with previous approach. For image quality measurement we will use some scientific parameters those are PSNR, SSIM, FSIM. Implementation of proposed algorithm will be done by Matlab and hardware implementation will be done by using of Verilog on Xilinx 14.1 simulator. Verification will be done on Model sim.

Various clustering algorithms are tested on the log data to group locations. The final algorithm uses K-means clustering on latitude/longitude to assign Area Codes, hierarchical clustering on access point visibility to assign Visibility Codes, and signal strength differences to assign Power Codes. Code and diagrams generated in R are discussed as validating the location grouping method.
AN ENHANCED BLOCK BASED EDGE DETECTION TECHNIQUE USING HYSTERESIS THRESHOLDING sipij
Edge detection is a crucial step in various image processing systems like computer vision , pattern
recognition and feature extraction. The Canny edge detection algorithm even though exhibits high
accuracy, is computationally more complex compared to other edge detection techniques. A block based
distributed edge detection technique is presented in this paper, which adaptively finds the thresholds for
edge detection depending on block type and the distribution of gradients in each block. A novel method of
computation of high threshold has been proposed in this paper. Block-based hysteresis thresholds are
computed using a non uniform gradient magnitude histogram. The algorithm exhibits remarkably high
edge detection accuracy, scalability and significantly reduced computational time. Pratt’s Figure of Merit
quantifies the accuracy of the edge detector, which showed better values than that of original Canny and
distributed Canny edge detector for benchmark dataset. The method detected all visually prominent edges
for diverse block size.
In this paper a novel edge detection method has been proposed which outperform Otsu method [1]. The proposed detection algorithm has been devised using the concept of genetic algorithm in spatial domain. The key of edge detection is the choice of threshold; which determines the results of edge detection. GA has been used to determine an optimal threshold over the image. Results are compared with existing Otsu technique which shows better performances
The document describes a modified Otsu method for edge detection using genetic algorithms. It begins with an introduction and literature review of existing edge detection techniques like Roberts, Sobel, and Prewitt operators as well as Otsu thresholding. The proposed technique uses genetic algorithms to determine an optimal threshold for edge detection. It initializes a population of threshold values as chromosomes, calculates their fitness based on class variance, and applies genetic operators like selection, crossover and mutation to arrive at the optimal threshold. Experimental results showed the modified Otsu method performed better than the original Otsu technique.
The document describes a 3D laser profiling system called the LCMS that can automatically measure road surface conditions like cracks, ruts, texture, and raveling. It does this using two high-resolution 3D laser profilers mounted on a vehicle that collect transverse road profiles up to 100km/h. Algorithms then analyze the 3D and intensity data to detect and classify various surface features. The LCMS was tested on over 10,000km of road network and showed over 95% accuracy in crack detection when compared to manual results. It provides reliable, continuous assessment of pavement conditions for maintenance planning.
Matching algorithm performance analysis for autocalibration method of stereo ...TELKOMNIKA JOURNAL
Stereo vision is one of the interesting research topics in the computer vision field. Two cameras are used to generate a disparity map, resulting in the depth estimation. Camera calibration is the most important step in stereo vision. The calibration step is used to generate an intrinsic parameter of each camera to get a better disparity map. In general, the calibration process is done manually by using a chessboard pattern, but this process is an exhausting task. Self-calibration is an important ability required to overcome this problem. Self-calibration required a robust and good matching algorithm to find the key feature between images as reference. The purpose of this paper is to analyze the performance of three matching algorithms for the autocalibration process. The matching algorithms used in this research are SIFT, SURF, and ORB. The result shows that SIFT performs better than other methods.
Deep Convolutional Neural Networks (CNNs) have achieved impressive performance in
edge detection tasks, but their large number of parameters often leads to high memory and energy
costs for implementation on lightweight devices. In this paper, we propose a new architecture, called
Efficient Deep-learning Gradients Extraction Network (EDGE-Net), that integrates the advantages of Depthwise Separable Convolutions and deformable convolutional networks (DeformableConvNet) to address these inefficiencies. By carefully selecting proper components and utilizing
network pruning techniques, our proposed EDGE-Net achieves state-of-the-art accuracy in edge
detection while significantly reducing complexity. Experimental results on BSDS500 and NYUDv2
datasets demonstrate that EDGE-Net outperforms current lightweight edge detectors with only
500k parameters, without relying on pre-trained weights.

edge detection tasks, but their large number of parameters often leads to high memory and energy
costs for implementation on lightweight devices. In this paper, we propose a new architecture, called
Efficient Deep-learning Gradients Extraction Network (EDGE-Net), that integrates the advantages of Depthwise Separable Convolutions and deformable convolutional networks (DeformableConvNet) to address these inefficiencies. By carefully selecting proper components and utilizing
network pruning techniques, our proposed EDGE-Net achieves state-of-the-art accuracy in edge
detection while significantly reducing complexity. Experimental results on BSDS500 and NYUDv2
datasets demonstrate that EDGE-Net outperforms current lightweight edge detectors with only
500k parameters, without relying on pre-trained weights.
Digital 3D imaging can be accelerated using advances in VLSI technology. High-resolution 3D images can be captured using laser-based vision systems, which produce 3D information insensitive to background illumination and surface texture. Complete images of featureless surfaces invisible to the human eye can be generated. Sensors for 3D digitization include position sensitive detectors and laser sensors. Continuous response position sensitive detectors provide precise centroid measurement while discrete response detectors are slower but more accurate. An integrated sensor architecture is proposed using a combination of these sensors to simultaneously measure color and 3D.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

MODEL-BASED EDGE DETECTOR FOR SPECTRAL IMAGERY USING SPARSE SPATIOSPECTRAL MASKS
1. MODEL-BASED EDGE DETECTOR FOR SPECTRAL IMAGERY USING
SPARSE SPATIOSPECTRAL MASKS
ABSTRACT
Two model-based algorithms for edge detection in spectral imagery are developed that
specifically target capturing intrinsic features such as isoluminant edges that are characterized by
a jump in color but not in intensity. Given prior knowledge of the classes of reflectance or
remittance spectra associated with candidate objects in a scene, a small set of spectral-band
ratios, which most profoundly identify the edge between each pair of materials, are selected to
define a edge signature. The bands that form the edge signature are fed into a spatial mask,
producing a sparse joint Spatiospectral nonlinear operator. The first algorithm achieves edge
detection for every material pair by matching the response of the operator at every pixel with the
edge signature for the pair of materials. The second algorithms a classifier-enhanced extension of
the first algorithm that adaptively accentuates distinctive features before applying the spatial
spectral operator. Both algorithms are extensively verified using spectral imagery from the
airborne hyper spectral imager and from a dots-in-a-well mid infrared imager. In both cases, the
multicolor gradient (MCG) and the hyper spectral/spatial detection of edges (HySPADE) edge
detectors are used as a benchmark for comparison. The results demonstrate that the proposed
algorithms outperform the MCG and HySPADE edge detectors in accuracy, especially when
isoluminant edges are present. By requiring only a few bands as input to the spatial spectral
operator, the algorithms enable significant levels of data compression in band selection. In the
presented examples, the required operations per pixel are reduced by a factor of 71 with respect
to those required by the MCG edge detector.
EXISTING SYSTEM
2. The extension of gray-scale edge detection to multicolor images has followed three
principal paths .A straight forward approach is to apply differential operators, such as the
gradient, separately to each image plane and then consolidate the information to obtain edge
information identified several key drawbacks of such a straightforward approach. First, edges
can be defined by combinations of different image planes and these edges may be missing in
some of the image planes. Second, processing image planes separately disregards potential
correlation across image planes. Third, integration of information from separate image planes is
not trivial and is often done in an ad hoc manner. Moreover, in cases when an edge appears only
in a subset of image planes, there are no standard ways to fuse the information from different
planes. In recent years, new gray-scale algorithms were presented in the community.
PROPOSED SYSTEM
The results demonstrate that the proposed algorithms outperform the MCG and
HySPADE edge detectors in accuracy, especially when isoluminant edges are Present. We
present the SRC and the ASRC algorithms. We present results of applying the algorithm to real
data and compare the performance to those resulting from the Canny, MCG and HySPADE edge
detectors. We present a complexity analysis of the algorithms. The dramatic reduction in the
number of operations with respect to other algorithms such as the MCG and the HySPADE
algorithms is a key advantage of the proposed algorithms. The reduced number of operations is
mainly due to the property that only a few bands are required to perform edge detection.
MODULES
1. Canny Algorithm
3. The Canny edge detector is an edge detection operator that uses a multi-stage algorithm to detect
a wide range of edges in images.
The Canny algorithm is adaptable to various environments. Its parameters allow it to be tailored
to recognition of edges of differing characteristics depending on the particular requirements of a
given implementation.
Good detection – the algorithm should mark as many real edges in the image as
possible.
Good localization – edges marked should be as close as possible to the edge in the
real image.
2. MCG Edge Detection (Multi color Gradient)
A second approach for multicolor edge detection is to embed the variations of all color channels
in a single measure, which is then used to obtain the edge maps. Typically, this approach is
developed by starting from a given gray-scale operator, which is then consistently extended to
multi color images.
3. HySPADE Detection Algorithm
Hyper spectral imaging, like other spectral imaging, collects and processes information from
across the electromagnetic spectrum. The goal of hyper spectral imaging is to obtain the
spectrum for each pixel in the image of a scene, with the purpose of finding objects, identifying
materials, or detecting processes.
4. SRC Algorithm (Spectral Ratio Contrast)
4. Spectral Ratio Contrast (SRC) edge detection algorithm, defines the edge map of a spectral
image by matching the output of the 3D mask with the ratios from the edge signature.
In conjunction with a spatial mask, the few spectral bands from the edge signature give rise to a
multispectral operator that can be viewed as a sparse, three-dimensional (3D) mask, which is at
the heart of the two proposed edge-detection algorithms.
5. ASRC Algorithm (Adaptive Spectral Ratio Contrast)
Adaptive Spectral Ratio Contrast (ASRC) edge detection algorithm since it adaptively changes
the SRC algorithm sensitivity to edges (at each pixel) by considering the material-classification
results of the neighboring pixels.
The first algorithm detects edges that arise from both intensity and spectral changes while the
second algorithm detects edges based on spectral changes only.
