Abstract:
1. A video processing apparatus with residue prediction of a current video frame spatially partitioned into a plurality of blocks, comprising: a motion estimation/compensation unit for determining a matching block of a reference video frame according to a current block of the current video frame, acquiring neighboring reconstructed pixels adjacent to the current block, and retrieving corresponding pixels adjacent to the matching block by aligning the neighboring reconstructed pixels with a motion vector of the current block, wherein the motion vector represents a displacement between the current block and the matching block; a pseudo-residue generating unit for constructing a set of pseudo residues according to the neighboring reconstructed pixels in the current video frame and the corresponding pixels in the reference video frame; a first arithmetic unit for generating first-order residues by subtracting the matching block from the current block; a residue-predicting unit coupled to the pseudo-residue generating unit for employing the set of pseudo residues to predict the first-order residues and derive second-order residues and corresponding residue prediction information for the current block; and a post-processing unit coupled to the residue-predicting unit for deriving a reconstructed current block according to the second-order residues and the corresponding residue prediction information for encoding subsequent blocks within the current video frame.
