Edge is the boundary between the image and its background. Edge detection in general is defined as the local maxima obtained from high pass filters, but an optimized edge detector should mark the edges with respect to luminance or brightness changes. It is easy to obtain them in software implementation but for hardware implementation there is an issue with percentage of accuracy and processing time. This study discusses various edge detection algorithms and proposes an optimized edge detector which provides the solution for mentioned above issue. Since FPGA provides practical solutions for most of the image processing problems, the proposed architecture has been developed using Matlab System generator. Experimental results show the accuracy of edge detected using proposed architecture.
