Abstract: A method for adaptive pre-filtering is disclosed, comprising the steps of extracting tuning parameters from video encoding process; processing these tuning parameters to generate control parameters representative of the properties of the video data processed; coupling the control parameters to filter response; generating filter coefficients on selected filter response; and filtering the video data with the filter coefficients before video encoding. The filtering of video data is thus adapted to at least one or more tuning parameters of the video data and the encoding process. The filtering decreases the complexity of encoding by attenuation of high frequency, effectively decreasing the quantization step and reducing compression artifacts.

Abstract: A system and method for video noise reduction using motion and edge adaptive temporal-spatial filtering is disclosed in the present invention. The system includes a motion and edge adaptive temporal-spatial filter and an impulse noise filter which can reduce both Gaussian and impulse noise within the video signals. A spatial filter is used to define the pixel value for the motion pixels. A temporal noise filter is used to define the current pixel value for the still pixels. A motion detector and a tail-detector is used to distinguish between moving and non-moving image areas, In regions where the status of a pixel changes from static to motion, the spatial and temporal filter results are mixed for the system video output. However, if impulse noise is detected, an impulse noise filtered video output is used for the system video output.
