Abstract

Edge detection is an image processing technique for finding the boundaries of objects within images. It works by detecting discontinuities in brightness. Edge detection is used for image segmentation and data extraction in areas such as image processing, computer vision, and machine vision. ....etc

An improved new approach to identifying the person using the iris recognition technique. This approach is based on the Artificial Neural Network and Vector Support Machine (SVM) as an iris pattern classifier. Prior to the classifier, the region of interest, ie the iris region, is segmented using the Canny edge detector and the Hough transform. Provided that the effect of the eyelid and the eyelashes is reduced. The Daugman rubber sheet model is used to obtain the standardised iris to improve computational efficiency and proper dimensionality. I ....etc

Accurate measurement and classification of blood vessels could provide useful information to clinical diagnosis. Abnormalities in diameter of retinal blood vessels and presence of unusual
artefacts on retinal image are usually the first clinical finding in many retinal diseases, like diabetic retinopathy etc. Manual segmentation of retinal blood vessels is a long and tedious task
which also requires skill. That is why automatic delineation and classification of retinal vessels, and general evaluation of retinal images is the first step in the d ....etc

matlab code for feature extraction from image for signature

Abstract

Signature verification is one of the most accepted biometric techniques, because a signature is a part of everyday life, although less accurate than biometric techniques such as using the iris. In this field, much attention has been paid to features, because a verification system should be able to overcome problems such as forgeries, insensitivity to intra-personal variability and sensitivity to inter-personal variability. In this paper, we present a simple and efficient app ....etc

matlab code for retinal image optic disc extraction

Abstract

In this article, we propose a new method for localizing optic disc in retinal images. Localizing the optic disc and its center is the first step of most vessel segmentation, disease diagnostic, and retinal recognition algorithms. We use optic disc of the first four retinal images in DRIVE dataset to extract the histograms of each color component. Then, we calculate the average of histograms for each color as template for localizing the center of optic disc. The DRIVE, STARE, and a l ....etc

Description
The m-files inside this zip file extracts features of single characters of english language based on their geometric properties from the input image. Two approaches are explained for extracting feature vectors. The final feature vector generated for my purpose had more 120 elements. The features are based on the basic geometric shapes that comprises a single character. It calculates how many basic line segments are there in the given character. Basic line segments like horizontal, vertical and diagonal are what looked for. Their len ....etc
