Some image processing algorithms on a RAP with wider bus networks

Based on the reconfigurable array of processors with wider bus networks (Li et al., 1995), we propose a series of algorithms for image processing. Conventionally, only one bus is connected between two processors but in this machine it has a set of buses. Such a characteristic increases the computation power of this machine greatly. Based on the base-m number system, we first introduce some basic operation algorithms. Then three related applications are derived in constant time; one is the histogram of an image, another is the image segmentation and the other is the image labeling.
