Abstract: Medical imaging is an important means of medical diagnosis. In the early diagnosis of some diseases, tissue information represents important characteristic data and plays a crucial role in the diagnosis of diseases. Therefore, accurate and clear image segmentation of medical images has a great effect on the accuracy of medical diagnosis. In order to improve the efficiency and speed of computing, this ariticle use FPGA devices with parallel computing power to extract image edges. Finally, the simulation on the Quartus platform has been done and the precise image edges are obtained.
