Abstract: This paper presents the parallel multicore Sobel edge algorithm which parallelizes the traditional sequential Sobel edge detection algorithm on a parallel multicore platform. Dealing with images, the algorithm inherits repetitive instructions that depend on the image size, thus may slow down the processing speed. The multicore architecture is a ready available resource on ordinary personal computer but often not fully utilized to its utmost potential. Align with this hidden opportunity, Sobel edge algorithm can be implemented on parallel programming paradigm by focusing on the thread operations. This work presents the parallel multicore Sobel edge algorithm which parallelizes the traditional sequential Sobel edge detection algorithm on a parallel multicore platform via Parallel communication software named Message Passing Interface (MPI). The test is being done on ten different images with each image tested in the varying size of 1KxK, 2KxK and 3KxK pixels. Variou!
s threads, ranging from two to ten had been performed on Duo and Quad cores. An interesting result shows that in sequential processing Duo core overcome Quad core speed. As for parallel processing, two thread is the best used for Duo core and eight threads is finest for Quad core.
Keywords: Parallel programming, Sobel edge algorithm, Message passing interface , Multicore.
