TL;DR: In this paper, a motion compensated temporal filtering using previously generated motion vectors and adaptive spatial filtering at scene change frames is proposed to reduce the noise in a video system by applying motion compensation and adaptive spatio-temporal filtering.
Patent
Motion compensated temporal filtering for noise reduction pre-processing of digital video data
Siu-Wai Wu,Jing Yang Chen +1 more
TL;DR: In this article, a single stage P-frame and double stage B-frame temporal noise filtering was proposed to reduce the noise in a video system by using previously generated motion vectors and adaptive spatial filtering at scene change frames.
Patent
Motion-adaptive noise reduction pre-processing for digital video signal
Siu-Wai Wu,Jing Yang Chen +1 more
TL;DR: In this paper, a video system is reduced by applying motion compensated temporal filtering using previously generated motion vectors and adaptive spatial filtering at scene change frames, which improves on previous filtering techniques by using the Infinite Impulse Response (IIR) temporal filtering.
