Firstly, order morphological transformations on gray image are introduced in this paper, then an image processing system in which order morphological transformation is implemented by hardware is presented. The system is composed of Digital Signal Processor (DSP) and Field Programmable Gate Array (FPGA), one FPGA as coprocessor can implement different functions due to its re-configurable characteristic. The images processed by software and hardware realization are compared in effect and speed. The algorithm is implemented successfully and its speed is very high. It makes possible that mathematical morphology is applicable in real time image processing.
