Roberts edge detection algorithm based on GPU

Abstract

With the development of the semiconductor technolog y, the GPU’s floating point computing capacity impr oves rapidly. How to apply the GPU technology to the non-graphic computing field becomes a highlight in the research of high performance computing. The Roberts edge detection a lgorithm is a typical image processing algorithms. A fast Roberts edge detection algorithm is presented based on GPU, Texture memory technology and asynchronous data transmission are adopted to optimize the applicatio n of the algorithm. The experiment expressed that w e could get a over ten times speed effect by this method than tra ditional Roberts edge detection algorithm.
