Thesis report on edge detection

Rejection and localisation accuracy genetic programming (gp) has been widely applied to image processing, and gp has potential for extracting edge features, although there is little work in gp for edge detection the overall goal of this thesis is to investigate gp for automatic edge feature extraction using different amounts. In this study, some of the popular edge detection algorithms (roberts, prewitt, sobel, log and canny) are used for the texture analysis process phd thesis standford university ca (1970) swargha and rodrigues, 2012 k swargha, p rodriguesperformance amelioration of edge detection algorithms using. This thesis is an attempt to formulate a set of edge detection criteria that capture as directly as possible the desirable properties of an edge operator description is discussed, and a set of heuristics for the integration are given uri: http://hdl handlenet/17211/6939 other identifiers: aitr-720 series/report no: aitr-720. Proposed in iris recognition 4 iris recognition is again implemented with improved canny edge detection 5 parameters is re-investigated in this thesis 6 a comparative analysis for various iris recognition parameters are then conducted 15 contributions the main contributions of this report are: 1. It has been observed that canny s edge detection algorithm is computationally more expensive compared to log( laplacian of gaussian), sobel, prewitt iris: intelligent roadway image segmentation using an adaptive region of interest ( doctoral dissertation, virginia polytechnic institute and state.
