Abstract

The unsharp masking algorithm is an effective method for image spatial domain enhancement. The improved unsharp masking algorithm can achieve the sharpening effect of edge enhancement while suppressing noise. However, it is difficult to implement in real-time image processing systems due to the need to perform multiple spatial domain filtering and a large amount of calculation. In this paper, an improved unsharp masking image enhancement algorithm is implemented on FPGA. Compared with the software implementation, time optimization has been carried out to meet the requirements of real-time processing of video streams, and it can achieve edge enhancement while suppressing noise to meet the performance needs of real-time video processing.
