Abstract
A method and apparatus for adaptive denoising of source video in a video conference application is provided. Source video frames received from a video capture device are divided into a plurality of 16×16 blocks. For each source block, a moving object detection process and a noise estimation process are performed. Then temporal denoising is adaptively applied to the blocks of the source frame based on the noise estimation and moving object detection. The adaptively filtered blocks are provided to an output frame and forwarded to a coding module for encoding.
