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.
Key words: Edge detection, FPGA, image processing, Matlab (system generator), xilinx (IP core), ,
