Adaptive Temporal Filter Based on Motion Compensation for Video Noise Reduction

Noise in video signals will degrade the quality of image.A temporal adaptive filter based on a motion-compensation is proposed for noise reduction.The noise in video sequence is tracked by the motion-compensation in temporal domain.The filtering strength can be adaptively changed on the motion situation of a subject.The experimental results show that the proposed filter is better than that in spatial domain.The noise in video signals can be effectively reduced and the image will not be so blurry as the result of spatial filter.
