high performance computing on graphics processing units: hgpu.org

With the development of the semiconductor technology, the GPU’s floating point computing capacity improves 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 algorithm 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 application of the algorithm. The experiment expressed that we could get a over ten times speed effect by this method than traditional Roberts edge detection algorithm.
