Implementing Real Time Image Processing Algorithm on FPGA

摘要

FPGA is popular for real time image process attributed to its flexibility and parallelism. In this paper, a parallel fast median filtering algorithm is implemented by FPGA. The times of comparison can be reduced by half compared to the bubble sort method. To keep more border information of image, an efficient implement of border management is proposed in detail. Meanwhile, a speed up method presented is more effective in the real-time application. The proposed method shows good performance in eliminating noise. The low resource consuming and the low latency is meaningful for real time image processing application.
