A device for motion-compensated recursive filtering of video images before coding, the coding system and corresponding method

摘要

(57) [Abstract] The present invention relates to a coding system and apparatus and method for motion compensated recursive filtering, the corresponding. In particular, the module that calculates block motion estimation module (2), means for determining the (σ _rec) recursive noise level (3), the prediction error (ε) and (4), the device, recursive noise level Filter module for calculating the recursive coefficients as a function of the prediction error as a function of the (α) and (5), means for calculating an image that is motion-compensated and (6), the recursive coefficients, stored in advance with the current input image I and a (7,8) filter means for outputting the weight of the image that is motion-compensated and the. The device also is lower than the threshold for processing the region constituting means for determining the (σ _imm) immobilized noise level (3), the boundaries of the block used for motion estimation, FDs depends on the immobilization noise level includes assembly to zero (d) and (11, 12) the motion vector for engaging the region,
