With the fast development of electronic technology, real-time image processing technique is widely used in the fields such as multimedia and image communication and so on. In these systems of digital image processing, a question is put forward on how to process a large amount of real-time image data. Especially, in the fields which need high resolution and good real-time requirements, FPGA now has became an ideal choice of hardware in real-time image processing because of high processing speed, while the re...
