Abstract: Provided is an illumination and contrast compensation method applied to the frames comprising multi-view video sequence. Relations between the values of the pixels of the reference block and the values of the pixels neighboring the reference block and relations between the restored values of the pixels neighboring the current block and the values of the pixels neighboring the reference block is determined. An illumination and contrast compensation parameters for illumination and contrast compensation of discrepancy (mismatch) compensation between reference and encoded blocks is determined on the basis of the determined relations, values of the pixels of the reference block, restored values of the pixels neighboring the current block and values of the pixels neighboring the reference block.

Abstract: A motion estimation method for video data including frames and an apparatus therefor are provided. The motion estimation method includes determining whether a current frame unit for which motion estimation is to be performed corresponds to a double block, when the current frame unit corresponds to a double block, acquiring a candidate vector set corresponding to a first single block included in the double block, as a candidate vector set of the double block, individually calculating a confidence function value of each candidate vector included in the candidate vector set of the double block, for the first single block and a second single block included in the double block, and acquiring an estimated motion vector of the first single block and an estimated motion vector of the second single block, based on the calculated confidence function value of each candidate vector.

Abstract: A video frame rate conversion (FRC) method, including obtaining at least one pair of frames of a video; partitioning each frame into a plurality of blocks; estimating motion a block-by-block basis to obtain: a forward motion field including a set of first motion vectors, and a backward motion field including a set of second motion vectors; obtaining occlusions based on the forward motion field and the backward motion field; and calculating an artifact probability metric indicating a probability of an appearance of an artifact in the motion-compensated frame interpolation between the first frame and the second frame.
