基于时域的视频去噪算法研究
Research on noise elimination algorithms of videos based on time domain
摘要
Abstract
Two noise elimination algorithms of videos based on time domain are discussed. The time domain filtering based on diamond motion estimation is introduced. The diamond motion estimation is conducted to search for the optimal matching block, and between the two blocks is proceeded with mean filtering. The filtered image is output after matching blocks integration. The BM3D noise elimination technology of videos is presented,and the main process of this technology is described in detail. The principles and process of block matching,three⁃dimensional transformation domain filtering,weight calculation and reconstruc⁃tion in noise elimination process are explained respectively. The experimental results verify that the two methods can achieve good effect in the aspect of noise elimination.关键词
