Noise Robust Motion Refinement for Motion Compensated Noise Reduction

A motion refinement algorithm is proposed to enhance motion compensated noise reduction (MCNR) efficiency. Instead of the vector with minimum distortion, the vector with minimum distance from motion vectors of neighboring blocks is selected as the best motion vector among vectors which have distortion values within the range set by noise level. This motion refinement finds more accurate motion ...

Motion-Compensated Noise Reduction in B&W Motion Picture Films

Blotchy noise is one of the most common and visually annoying noises noticed in digitized black-and-white motion picture films. This work investigates presents a three-stage blotchy noise reduction scheme combining efforts of temporal median filtering and motioncompensated filtering after joint motion/noise detection. Implementation of each module of the scheme is discussed and finally performa...

Adaptive Deringing and Mosquito Noise Reducer

In this paper, we propose an efficient algorithm to reduce the ringing and temporal noise artifacts in block based video coding. This algorithm operates adaptively on an 8x8 block basis. Temporally non-static blocks are spatially filtered, whereas temporally static blocks are filtered in both spatial and temporal directions. Experimental results show that the presented method considerably impro...
