Non-local mean-based video denoising method and apparatus

摘要

The present disclosure provides a non-local mean-based video denoising method, so as to remove illumination variation in a video by using image histogram specification filtering processing. The present disclosure further provides a non-local mean-based video denoising apparatus.
