Review and comparison of tasks scheduling in cloud computingijfcstjournal
Recently, there has been a dramatic increase in the popularity of cloud computing systems that rent
computing resources on-demand, bill on a pay-as-you-go basis, and multiplex many users on the same
physical infrastructure. It is a virtual pool of resources which are provided to users via Internet. It gives
users virtually unlimited pay-per-use computing resources without the burden of managing the underlying
infrastructure. One of the goals is to use the resources efficiently and gain maximum profit. Scheduling is a
critical problem in Cloud computing, because a cloud provider has to serve many users in Cloud
computing system. So scheduling is the major issue in establishing Cloud computing systems. The
scheduling algorithms should order the jobs in a way where balance between improving the performance
and quality of service and at the same time maintaining the efficiency and fairness among the jobs. This
paper introduces and explores some of the methods provided for in cloud computing has been scheduled.

Object Recogniton Based on Undecimated Wavelet TransformIJCOAiir
Object Recognition (OR) is the mission of finding a specified object in an image or video sequence
in computer vision. An efficient method for recognizing object in an image based on Undecimated Wavelet
Transform (UWT) is proposed. In this system, the undecimated coefficients are used as features to recognize the
objects. The given original image is decomposed by using the UWT. All coefficients are taken as features for
the classification process. This method is applied to all the training images and the extracted features of
unknown object are used as an input to the K-Nearest Neighbor (K-NN) classifier to recognize the object. The
assessment of the system is agreed on using Columbia Object Image Library Dataset (COIL-100) database.
An Approach for Iris Recognition Based On Singular Value Decomposition and Hi...paperpublications3
Abstract: This paper presents a new approach using Hidden Markov Model as classifier and Singular Values Decomposition (SVD) coefficients as features for iris recognition. As iris is a complex multi-dimensional structure and needs good computing techniques for recognition and it is an integral part of biometrics. Features extracted from a iris are processed and compared with similar irises which exist in database. The recognition of human irises is carried out by comparing characteristics of the iris to those of known individuals. Here seven state Hidden Markov Model (HMM)-based iris recognition system is proposed .A small number of quantized Singular Value Decomposition (SVD) coefficients as features describing blocks of iris images. SVD is a method for transforming correlated variables into a set of uncorrelated ones that better expose the various relationships among the original data item. This makes the system very fast. The proposed approach has been examined on CASIA database. The results show that the proposed method is the fastest one, having good accuracy.
Image fusion is a sub field of image processing in which more than one images are fused to create an image where all the objects are in focus. The process of image fusion is performed for multi-sensor and multi-focus images of the same scene. Multi-sensor images of the same scene are captured by different sensors whereas multi-focus images are captured by the same sensor. In multi-focus images, the objects in the scene which are closer to the camera are in focus and the farther objects get blurred. Contrary to it, when the farther objects are focused then closer objects get blurred in the image. To achieve an image where all the objects are in focus, the process of images fusion is performed either in spatial domain or in transformed domain. In recent times, the applications of image processing have grown immensely. Usually due to limited depth of field of optical lenses especially with greater focal length, it becomes impossible to obtain an image where all the objects are in focus. Thus, it plays an important role to perform other tasks of image processing such as image segmentation, edge detection, stereo matching and image enhancement. Hence, a novel feature-level multi-focus image fusion technique has been proposed which fuses multi-focus images. Thus, the results of extensive experimentation performed to highlight the efficiency and utility of the proposed technique is presented. The proposed work further explores comparison between fuzzy based image fusion and neuro fuzzy fusion technique along with quality evaluation indices.

A Pattern Classification Based approach for Blur Classificationijeei-iaes
Blur type identification is one of the most crucial step of image restoration. In case of blind restoration of such images, it is generally assumed that the blur type is known prior to restoration of such images. However, it is not practical in real applications. So, blur type identification is extremely desirable before application of blind restoration technique to restore a blurred image. An approach to categorize blur in three classes namely motion, defocus, and combined blur is presented in this paper. Curvelet transform based energy features are utilized as features of blur patterns and a neural network is designed for classification. The simulation results show preciseness of proposed approach.
Development of 3D convolutional neural network to recognize human activities ...journalBEEI
Human activity recognition (HAR) is recently used in numerous applications including smart homes to monitor human behavior, automate homes according to human activities, entertainment, falling detection, violence detection, and people care. Vision-based recognition is the most powerful method widely used in HAR systems implementation due to its characteristics in recognizing complex human activities. This paper addresses the design of a 3D convolutional neural network (3D-CNN) model that can be used in smart homes to identify several numbers of activities. The model is trained using KTH dataset that contains activities like (walking, running, jogging, handwaving handclapping, boxing). Despite the challenges of this method due to the effectiveness of the lamination, background variation, and human body variety, the proposed model reached an accuracy of 93.33%. The model was implemented, trained and tested using moderate computation machine and the results show that the proposal was successfully capable to recognize human activities with reasonable computations.

SAR Image Classification by Multilayer Back Propagation Neural NetworkIJMTST Journal
A novel descriptive feature extraction method of Discrete Fourier transform and neural network classifier for classification of Synthetic Aperture Radar (SAR) images is proposed. The classification process has the following stages (1) Image Segmentation using statistical Region Merging (SRM) (2) Polar transform and Feature extraction using Discrete Fourier Transform (3) Neural Network classification using back propagation. This is generally the first step in image analysis. Segmentation subdivides an image into its constituent parts or objects. The level to which this subdivision is carried depends on the problem being solved. The image segmentation in this study is performed using Statistical Region Merging proposed Richard Nock and Frank Nielsen. The key idea of the Statistical Region Merging model is to formulate image segmentation as an inference problem. Here the merging procedure is based on the theorem. Feature vectors as the input for the neural network. Polar transform is applied to segmented SAR image. The rotation problem under the Cartesian coordinates becomes the translation problem under the polar coordinates.

Abstract
Feature-based image matching is an important characteristic in many computer based applications such as object recognition, 3D stereo reconstruction, structure-from-motion and images stitching. These applications require a lot real-time performance. Feature based algorithms are well-suited for such operations. Different algorithms are used for image processing like Scale-invariant feature transform (SIFT), Speeded up Robust Features (SURF), Oriented FAST and Rotated BRIEF (ORB). ORB is one of the fast binary descriptor which is relying on BRIEF, where the BRIEF is rotation invariant and resistant to noise. This paper gives the advantages of rotation invariance and scale invariance of ORB algorithm for object detection technique. Query based object detection method is explained in this paper for object detection with efficient computation time. Different experimental results prove the scale invariance and rotation in variance of ORB in query based object detection method.

This paper presents SimCLR: a simple framework for contrastive learning of visual representations. We simplify recently proposed contrastive self-supervised learning algorithms without requiring specialized architectures or a memory bank. In order to understand what enables the contrastive prediction tasks to learn useful representations, we systematically study the major components of our framework. We show that (1) composition of data augmentations plays a critical role in defining effective predictive tasks, (2) introducing a learnable nonlinear transformation between the representation and the contrastive loss substantially improves the quality of the learned representations, and (3) contrastive learning benefits from larger batch sizes and more training steps compared to supervised learning. By combining these findings, we are able to considerably outperform previous methods for self-supervised and semi-supervised learning on ImageNet. A linear classifier trained on self-supervised representations learned by SimCLR achieves 76.5% top-1 accuracy, which is a 7% relative improvement over previous state-of-the-art, matching the performance of a supervised ResNet-50. When fine-tuned on only 1% of the labels, we achieve 85.8% top-5 accuracy, outperforming AlexNet with 100X fewer labels.

Fuzzy Type Image Fusion Using SPIHT Image Compression TechniqueIJERA Editor
This paper presents a fuzzy type image fusion technique using Set Partitioning in Hierarchical Trees (SPIHT).
It is concluded that fusion with higher single levels provides better fusion quality. This technique can be used
for fusion of fuzzy images as well as multi model image fusion. The proposed algorithm is very simple, easy to

APPLICATION OF IMAGE FUSION FOR ENHANCING THE QUALITY OF AN IMAGEcscpconf
Advances in technology have brought about extensive research in the field of image fusion.
Image fusion is one of the most researched challenges of Face Recognition. Face Recognition
(FR) is the process by which the brain and mind understand, interpret and identify or verify
human faces.. Image fusion is the combination of two or more source images which vary in
resolution, instrument modality, or image capture technique into a single composite
representation. Thus, the source images are complementary in many ways, with no one input
image being an adequate data representation of the scene. Therefore, the goal of an image
fusion algorithm is to integrate the redundant and complementary information obtained from
the source images in order to form a new image which provides a better description of the scene
for human or machine perception. In this paper we have proposed a novel approach of pixel
level image fusion using PCA that will remove the image blurredness in two images and
reconstruct a new de-blurred fused image. The proposed approach is based on the calculation
of Eigen faces with Principal Component Analysis (PCA). Principal Component Analysis (PCA)
has been most widely used method for dimensionality reduction and feature extraction

Abstract
To store digital image and video in raw form require large amount of memory space. Image compression means reducing the size of image file without degrading quality of image. Depending on the reconstructed image to be exactly same as the original or some unknown loss may incurred image compression divided into two techniques lossy and lossless techniques. In this paper we present hybrid model which is the combination of several compression techniques. This paper present DWT, DCT and SPIHT implementation. Simulation has been carried out on different images like Lena , Barbra, Cameraman, Test drive . Result analysis is done through parameters like MSE, PSNR and Elapsed time. Values of this parameters will go better than the old algorithms because here we apply SPIHT lossless technique and also due to hybrid combination of DWT and DCT we will get good level of compression. The result analysis shows that the proposed hybrid algorithm performs much better in terms of PSNR with a higher compression ratio as compared to standalone DWT and DCT techniques.

Faster Training Algorithms in Neural Network Based Approach For Handwritten T...CSCJournals
Handwritten text and character recognition is a challenging task compared to recognition of handwritten numeral and computer printed text due to its large variety in nature. As practical pattern recognition problems uses bulk data and there is a one step self sufficient deterministic theory to resolve recognition problems by calculating inverse of Hessian Matrix and multiplication the inverse matrix it with first order local gradient vector. But in practical cases when neural network is large the inversing operation of the Hessian Matrix is not manageable and another condition must be satisfied the Hessian Matrix must be positive definite which may not be satishfied. In these cases some repetitive recursive models are taken. In several research work in past decade it was experienced that Neural Network based approach provides most reliable performance in handwritten character and text recognition but recognition performance depends upon some important factors like no of training samples, reliable features and no of features per character, training time, variety of handwriting etc. Important features from different types of handwriting are collected and are fed to the neural network for training. It is true that more no of features increases test efficiency but it takes longer time to converge the error curve. To reduce this training time effectively proper train algorithm should be chosen so that the system provides best train and test efficiency in least possible time that is to provide the system fastest intelligence. We have used several second order conjugate gradient algorithms for training of neural network. We have found that Scaled Conjugate Gradient Algorithm , a second order training algorithm as the fastest for training of neural network for our application. Training using SCG takes minimum time with excellent test efficiency. A scanned handwritten text is taken as input and character level segmentation is done. Some important and reliable features from each character are extracted and used as input to a neural network for training. When the error level reaches into a satisfactory level (10 -12 ) weights are accepted for testing a test script. Finally a lexicon matching algorithm solves the minor misclassification problems.
