Improvement and Implementation of FPGA-based Median Filtering Algorithm
Aiming at addressing sluggish processing,excessive arithmetic operation for sequencing,and poor details with respect to the currently prevailing median filtering algorithms,this work made an attempt to design an improved cross-type fast median filtering algorithm with the features of threshold-based comparison,higher processing speed,and better performance,and to implement it on the FPGA hardware platform.The improved algorithm was proved by a comparative experiment to have many advantages such as fewer comparison times,less hardware resources utilization,and better re-tention of image details,and to achieve a processing utility technically adequate for real-time image preprocessing.
