Abstract

Aiming at the difficulty of real-time and high-speed processing of the filtering process using software methods in image preprocessing, a fast median filtering algorithm based on FPGA is designed using the parallel processing capability of field programmable gate array (FPGA). Compared with the traditional median filtering algorithm, it has a great improvement, reducing the number of data comparisons and improving the processing speed. From the results of the Matlab and Modelsim joint simulation experiments, it can be seen that the filtering algorithm has a good filtering effect and can be fast, Efficiently filter the image, which helps to improve the quality of image processing.

Keywords
