چکیده

In this paper, a new method for edge detection in presence of impulsive noise based into the use of Support Vector Machines (SVM) is presented. This method shows how the SVM can detect edge in an efficient way. The noisy images are processed in two ways, first reducing the noise by using the SVM regression and then performing the classification using the SVM classification. The results presented show that this method is better than the classical ones when the images are affected by impulsive noise and, besides, it is well suited when the images are not noisy.

Noisy images edge detection: Ant colony optimization algorithm

The edges of an image define the image boundary. When the image is noisy, it does not become easy to identify the edges. Therefore, a method requests to be developed that can identify edges clearly in a noisy image. Many methods have been proposed earlier using filters, transforms and wavelets with Ant colony optimization (ACO) that detect edges. We here used ACO for edge detection of noisy ima...

Face Recognition using Eigenfaces , PCA and Supprot Vector Machines

This paper is based on a combination of the principal component analysis (PCA), eigenface and support vector machines. Using N-fold method and with respect to the value of N, any person’s face images are divided into two sections. As a result, vectors of training features and test features are obtain ed. Classification precision and accuracy was examined with three different types of kernel and...

A FUZZY DIFFERENCE BASED EDGE DETECTOR

In this paper, a new algorithm for edge detection based on fuzzyconcept is suggested. The proposed approach defines dynamic membershipfunctions for different groups of pixels in a 3 by 3 neighborhood of the centralpixel. Then, fuzzy distance and -cut theory are applied to detect the edgemap by following a simple heuristic thresholding rule to produce a thin edgeimage. A large number of experime...

A Modified Median Filter for the Removal of Impulse Noise Based on the Support Vector Machines

In this work we present a new approach for the median filter. We modify this nonlinear filter used in impulse noise removal by applying it only to the noisy pixels and by using a different pixel as output of the modified filter. The decision between the noisy and no noisy pixels is implemented by using the Support Vector Machines classification. We use this new classification tool because of it...

A New and Improved Edge Detector Using the Support Vector Machines

In this paper, a new method for edge detection based on Support Vector Machines (SVM) is presented. This method improves our previous work in edge detection with SVM by reducing the execution time and upgrading the visual quality. Our work shows that a new training technique with a reduced set of vectors maintains the edge detection quality and then reduces the number of needed support vectors....
