There arises a need for automated and correct segmentation of exudates from digital fundus images. This paper proposes an automated computer vision technique for efficient exudates segmentation from fundus images. The proposed method segments the exudates using an adaptive intensity based threshold which is selected by strategically combining first order statistical parameters and local thresholding based method. The proposed technique correctly detects exudates from the fundus images with an average computation time of 9 seconds. The proposed method is computationally fast and can be used in image processing based applications for diagnosis of ocular diseases.","PeriodicalId":294210,"journal":{"name":"2016 Ninth International Conference on Contemporary Computing (IC3)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123572377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It initializes the weights of hidden neurons in a random manner and determines the output weights in an analytic manner by making use of Moore-Penrose (MP) generalized inverse. No-Prop algorithm is recently proposed training algorithm for feedforward neural networks in which the weights of the hidden neurons are randomly assigned and fixed, and the output weights are trained using least mean square error (LMS) algorithm. The difference between ELM and No-Prop lies in the way the output weights are trained. While ELM optimizes the output weights in batch mode using MP generalized inverse, No-Prop uses LMS gradient algorithm to train the output weights iteratively. In this paper, a comparative analysis based on empirical studies regarding the stability and convergence performance of ELM and No-Prop algorithms for data classification is provided.","PeriodicalId":294210,"journal":{"name":"2016 Ninth International Conference on Contemporary Computing (IC3)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125006891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of pansharpening is to enhance the spatial resolution of multispectral image while preserving its spectral information. The commonly used pansharpening methods like IHS, PCA, Gram Schmidt and Wavelet based method compromise either on spatial or spectral resolution. This paper presents a modified multiresolution analysis based pansharpening technique that is based on saliency detection of an image. This method fuses the spatial and spectral information of the images independently; therefore the fused image is obtained with high spatial as well as spectral information. The technique has been implemented on different datasets of multispectral and panchromatic images using different sets of fusion rules. The results reveal that the modified saliency detection based pansharpening technique performs better than the existing pansharpening technique and other commonly used pansharpening techniques.","PeriodicalId":294210,"journal":{"name":"2016 Ninth International Conference on Contemporary Computing (IC3)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115500307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The recognition rate and computational cost of proposed approach is examined against different wavelet families and Euclidean distance measure. Feature extraction is performed using Discrete wavelet transform and Principal component analysis (DWT-PCA). In order to explore best features, experiments are carried out for DWT subband selection and for DWT wavelet selection on Symlet family and on four other different wavelet families (Daubechies, Coiflets, Discrete Meyer and Biorthogonal wavelet family). This also includes their members that vary in terms of orthogonality, symmetry, support size, vanishing moments and filter order. After generating feature vectors, classification is done by Cosine angle distance measure based nearest neighbor classifier (NNC) and its results are compared with Euclidean distance measure. As test dataset, AT&T database of 400 images of 40 people is used to establish the performance by proposed approach.

The algorithm used for clustering directly influences the results obtained from applying the clustering algorithm (clusters). Data clustering is done in order to identify the patterns and trends not identifiable from just looking at the data. Clustering may be supervised (if the machine training data set is available) or unsupervised (if the machine training data set is not available). Unsupervised clustering is usually done using k-Means Algorithm (using any distance, the most common being Euclidean and Manhattan Distance). The drawback of k-means algorithm for a large set are the rigorous calculations that need to be done to cluster a data set into multiple data subsets for every single iteration, thereby limiting its efficiency and use for large data sets. We propose a range based single pass clustering algorithm that clusters data on the basis of the range which it falls in, where the ranges are calculated using simple arithmetic mean between two values. The proposed algorithm is compared against the standard k-means algorithm (using Euclidean Distance and Manhattan Distance).","PeriodicalId":294210,"journal":{"name":"2016 Ninth International Conference on Contemporary Computing (IC3)","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122278825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we are providing a hybrid GSABBO algorithm that will use the best properties of both the algorithm to enhance the exploration and exploitation properties and reach at the global optimal solution. Grid Computing refers to the sharing of resources across multiple domains to achieve a common goal. Sharing of the resources within an organization helps to enhance its overall performance computationally and economically. The advantages derived from Grid Computing are largely dependent on the scheduling algorithm we use to schedule various jobs across various resources available.

The proposed method includes a strategic windowing based approach for accurate detection of macula. Instead of searching macula from whole fundus image, a search region is considered with the help of optic disc and then macula is detected from that search region using double windowing based method. Normal and affected fundus images from a local eye hospital were used to test the performance of proposed method and achieved encouraging results.
