摘要: 該文在闡述了灰度圖像順序形態(tài)變換的基礎上，介紹了順序形態(tài)變換硬件實現(xiàn)的圖像處理系統(tǒng)。該系統(tǒng)采用DSP+FPGA的框架結構，利用FPGA的可重構特性將其中一片F(xiàn)PGA作為協(xié)處理器可以實現(xiàn)不同的圖像處理功能。文中將軟硬件實現(xiàn)的順序形態(tài)圖像處理圖片在處理效果和速度兩個方面作了比較。算法在FPGA芯片上的高速實現(xiàn)特征使數(shù)學形態(tài)學在圖像實時處理領域的應用成為可能。Abstract: 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 Pro-cessor (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.
