The fundamental task required for any image or Video processing applications like video surveillance, medical imaging is Edge detection. Any of the filters available can be used to detect the edges. In this paper Sobel Edge filter is used for comparing the performance analysis on CPUs and GPUs and from this study it is found that the performance analysis on GPUs is much higher as compared to CPUs. Also it is seen that parallel execution time is much less as compared to sequential execution for the heterogeneous systems.
