This document compares the performance of four face recognition algorithms - PCA, KPCA, KFA, and LDA - on three standard datasets: AT&T, Yale, and UMIST. It finds that KFA generally achieves the highest recognition rates, particularly for the AT&T and Yale datasets which involve changes in facial expressions and lighting. The Yale dataset, with its variations, yields the best results overall for KFA and LDA. The UMIST dataset, with its profile images, produces lower recognition rates across algorithms due to less similarity between training and test images.

Statistical Models for Face Recognition System With Different Distance MeasuresCSCJournals
Face recognition is one of the challenging applications of image processing. Robust face recognition algorithm should posses the ability to recognize identity despite many variations in pose, lighting and appearance. Principle Component Analysis (PCA) method has a wide application in the field of image processing for dimension reduction of the data. But these algorithms have certain limitations like poor discriminatory power and ability to handle large computational load. This paper proposes a face recognition techniques based on PCA with Gabor wavelets in the preprocessing stage and statistical modeling methods like LDA and ICA for feature extraction. The classification for the proposed system is done using various distance measure methods like Euclidean Distance(ED), Cosine Distance (CD), Mahalanobis Distance (MHD) methods and the recognition rate were compared for different distance measures. The proposed method has been successfully tested on ORL face data base with 400 frontal images corresponding to 40 different subjects which are acquired under variable illumination and facial expressions. It is observed from the results that use of PCA with Gabor filters and features extracted through ICA method gives a recognition rate of about 98% when classified using Mahalanobis distance classifier. This recognition rate stands better than the conventional PCA and PCA + LDA methods employing other and classifier techniques.
Feature selection using modified particle swarm optimisation for face recogni...eSAT Journals
Abstract
One of the major influential factors which affects the accuracy of classification rate is the selection of right features. Not all features have vital role in classification. Many of the features in the dataset may be redundant and irrelevant, which increase the computational cost and may reduce classification rate. In this paper, we used DCT(Discrete cosine transform) coefficients as features for face recognition application. The coefficients are optimally selected based on a modified PSO algorithm. In this, the choice of coefficients is done by incorporating the average of the mean normalized standard deviations of various classes and giving more weightage to the lower indexed DCT coefficients. The algorithm is tested on ORL database. A recognition rate of 97% is obtained. Average number of features selected is about 40 percent for a 10 × 10 input. The modified PSO took about 50 iterations for convergence. These performance figures are found to be better than some of the work reported in literature.
Keywords: Particle swarm optimization, Discrete cosine transform, feature extraction, feature selection, face recognition, classification rate.
Face Images Database Indexing for Person Identification ProblemCSCJournals
Face biometric data are with high dimensional features and hence, traditional searching techniques are not applicable to retrieve them. As a consequence, it is an issue to identify a person with face data from a large pool of face database in real-time. This paper addresses this issue and proposes an indexing technique to narrow down the search space. We create a two level index space based on the SURF key points and divide the index space into a number of cells. We define a set of hash functions to store the SURF descriptors of a face image into the cell. The SURF descriptors within an index cell are stored into kd-tree. A candidate set is retrieved from the index space by applying the same hash functions on the query key points and kd-tree based nearest neighbor searching. Finally, we rank the retrieved candidates according to their occurrences. We have done our experiment with three popular face databases namely, FERET, FRGC and CalTech face databases and achieved 95.57%, 97.00% and 92.31% hit rate with 7.90%, 12.55% and 23.72% penetration rate for FERET, FRGC and CalTech databases, respectively. The hit rate increases to 97.78%, 99.36% and 100% for FERET, FRGC and CalTech databases, respectively when we consider top fifty ranks. Further, in our proposed approach, it is possible to retrieve a set of face templates similar with query template in the order of milliseconds. From the experimental results we can substantiate that application of indexing using hash function on SURF key points is effective for fast and accurate face image retrieval.

Independent Component Analysis of Edge Information for Face RecognitionCSCJournals
In this paper we address the problem of face recognition using edge information as independent components. The edge information is obtained by using Laplacian of Gaussian (LoG) and Canny edge detection methods then preprocessing is done by using Principle Component analysis (PCA) before applying the Independent Component Analysis (ICA) algorithm for training of images. The independent components obtained by ICA algorithm are used as feature vectors for classification. The Euclidean distance and Mahalanobis distance classifiers are used for testing of images. The algorithm is tested on two different databases of face images for variation in illumination and facial poses up to 180 degree rotation angle.
Single Image Super-Resolution Using Analytical Solution for L2-L2 Algorithmijtsrd
This paper addresses a unified work for achieving single image super-resolution, which consists of improving a high resolution from blurred, decimated and noisy version. Single image super-resolution is also known as image enhancement or image scaling up. In this paper mainly four steps are used for enhancement of single image resolution: input image, low sampling the image, an analytical solution and L2 regularization. This proposes to deal with the decimation and blurring operators by their particular properties in the frequency domain, which leads to a fast super-resolution approach. And an analytical solution obtained and implemented for the L2-regularization i.e. L2-L2 optimized algorithm. This aims to reduce the computational cost of the existing methods by the proposed method.

Control chart pattern recognition using k mica clustering and neural networksISA Interchange
Automatic recognition of abnormal patterns in control charts has seen increasing demands nowadays in manufacturing processes. This paper presents a novel hybrid intelligent method (HIM) for recognition of the common types of control chart pattern (CCP). The proposed method includes two main modules: a clustering module and a classifier module. In the clustering module, the input data is first clustered by a new technique. This technique is a suitable combination of the modified imperialist competitive algorithm (MICA) and the K-means algorithm. Then the Euclidean distance of each pattern is computed from the determined clusters. The classifier module determines the membership of the patterns using the computed distance. In this module, several neural networks, such as the multilayer perceptron, probabilistic neural networks, and the radial basis function neural networks, are investigated. Using the experimental study, we choose the best classifier in order to recognize the CCPs. Simulation results show that a high recognition accuracy, about 99.65%, is achieved.
Threshold benchmarking for feature ranking techniquesjournalBEEI
In prediction modeling, the choice of features chosen from the original feature set is crucial for accuracy and model interpretability. Feature ranking techniques rank the features by its importance but there is no consensus on the number of features to be cut-off. Thus, it becomes important to identify a threshold value or range, so as to remove the redundant features. In this work, an empirical study is conducted for identification of the threshold benchmark for feature ranking algorithms. Experiments are conducted on Apache Click dataset with six popularly used ranker techniques and six machine learning techniques, to deduce a relationship between the total number of input features (N) to the threshold range. The area under the curve analysis shows that ≃ 33-50% of the features are necessary and sufficient to yield a reasonable performance measure, with a variance of 2%, in defect prediction models. Further, we also find that the log2(N) as the ranker threshold value represents the lower limit of the range.

In the present day automation, the researchers have been using microcomputers and its allies to carryout processing of physical quantities and detection of Cholesterol in blood and bio-medical Images. The latest trend is to use FPGA counter parts, as these devices offer many advantages in comparison with Programmable devices. These devices are very fast and involve hardwired logic. FPGA are dedicated hardware for processing logic and do not have an operating system. That means that speeds can be very fast and multiple control loops can run on a single FPGA device at different rates. In this paper, an attempt is being made to develop a prototype system to sense the Cholesterol portion in MRI image using modified Set Partitioning in Hierarchical Trees (SHIPT) wavelets transformation and Radial Basis Function (RBF). An each stage of Cholesterol detection are displayed on LCD monitor for clear view of improved version of MRI image and to find Cholesterol area. The performance parameters have been measured in terms of Peak Signal to Noise Ratio (PSNR), and Mean Square Error (MSE).

To handle this problem we used an effective semi-automatic annotation methodology with unsupervised label refinement (ULR) approach for refining the labels in facial images by using some machine learning techniques and fuzzy clustering-based approximation algorithm is used to improve the scalability considerably. Finally to develop an optimization algorithm for solving a large scale learning task. The result of this proposed ULR algorithm can improve the performance than other ULR algorithms in weak label matrix.

Speeded-up and Compact Visual Codebook for Object RecognitionCSCJournals
The well known framework in the object recognition literature uses local information extracted at several patches in images which are then clustered by a suitable clustering technique. A visual codebook maps the patch-based descriptors into a fixed-length vector in histogram space to which standard classifiers can be directly applied. Thus, the construction of a codebook is an important step which is usually done by cluster analysis. However, it is still difficult to construct a compact codebook with reduced computational cost. This paper evaluates the effectiveness and generalisation performance of the Resource-Allocating Codebook (RAC) approach that overcomes the problem of constructing fixed size codebooks that can be used at any time in the learning process and the learning patterns do not have to be repeated. It either allocates a new codeword based on the novelty of a newly seen pattern, or adapts the codebook to fit that observation. Furthermore, we improve RAC to yield codebooks that are more compact. We compare and contrast the recognition performance of RAC evaluated with two distinctive feature descriptors: SIFT and SURF and two clustering techniques: K-means and Fast Reciprocal Nearest Neighbours (fast-RNN) algorithms. SVM is used in classifying the image signatures. The entire visual object recognition pipeline has been tested on three benchmark datasets: PASCAL visual object classes challenge 2007, UIUC texture, and MPEG-7 Part-B silhouette image datasets. Experimental results show that RAC is suitable for constructing codebooks due to its wider span of the feature space. Moreover, RAC takes only one-pass through the entire data that slightly outperforms traditional approaches at drastically reduced computing times. The modified RAC performs slightly better than RAC and gives more compact codebook. Future research should focus on designing more discriminative and compact codebooks such as RAC rather than focusing on methods tuned to achieve high performance in classification.

Face recognition has gained significant attention in research community due to its wide range of commercial and law enforcement applications. Due to the developments in the past few decades, in the current scenario, face recognition is employing advanced feature identification techniques and matching methods. In spite of vast research done, face recognition still remains an open problem due to the challenges posed by illumination, occlusions, pose variation, scaling, etc. This paper is aimed at proposing a face recognition technique with high accuracy. It focuses on face recognition based on improved SIFT algorithm. In the proposed approach, the face features are extracted using a novel multi-kernel function (MKF) based SIFT technique. The classification is done using SVM classifier. Experimental results shows the superiority of the proposed algorithm over the SIFT technique. Evaluation of the proposed approach is done on CVL face database and experimental results shows that the proposed approach has a recognition rate of 99%.
Linearity of Feature Extraction Techniques for Medical Images by using Scale ...ijtsrd
In Machine Learning, Pattern Recognition and in the field of image processing, Feature Extraction starts from an initial set of the measured data. Builds derived values are intended to be informative and non redundant, facilating the subsequent learning and in some cases leading to the better human interpretations. Feature Extraction is a dimensionally reduction process, where an initial set of raw variables has been reduced to more manageable groups. Many data analysis software packages provide for feature extraction and for dimension reduction. Determining a subset of the initial features is also known as feature extraction. Common Numerical programming environments are MATLAB, SciLab, NumPy, etc. Ramar S | Keerthiswaran V | Karthik Raj S S "Linearity of Feature Extraction Techniques for Medical Images by using Scale Invariant Feature Transform" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-4 | Issue-3 , April 2020, URL: https://www.ijtsrd.com/papers/ijtsrd30358.pdf Paper Url :https://www.ijtsrd.com/engineering/bio-mechanicaland-biomedical-engineering/30358/linearity-of-feature-extraction-techniques-for-medical-images-by-using-scale-invariant-feature-transform/ramar-s

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
