| Abstract: | Aiming at the application of edge detection algorithm in image processing,an improved SUSAN algorithm is selected and implemented on FPGA.During this procedure,the operation template is appropriately chosen and,based on the issues of data selection,access,and pipeline design,the solution is proposed,including the module's multiplex,registers' circular shift and the combination technology of pipeline with line buffer.Such solution could fairly reduce the cost of hardware resource,save project bandwidth.The e... |
