However, to process a large amount of image data in real time requires a very high performance computer; after all, it is not possible in practice to adapt such a high performance visual system for the use of navigation vehicles and mobile robots. In this paper, a multi-resolution image frame processing method, which processes visual data functionally in a similar manner as a human retina, is presented. The multi-resolution image processing board is designed to have 4 kinds of image frames with different image resolutions. First image contours from the low-level resolution image frame are extracted. By moving to higher-level resolution image frames one operation after another to access image details and to perform motion analysis, the processing time can be reduced and the efficiency of the processing algorithm increased naturally. Consequently, this multi-resolution architecture enables to handle a huge image data more efficiently in real time than the conventional image processing board.
