Abstract: A technology for processing digital signals is provided, and more particularly, a method of encoding or decoding a multiview video sequence based on adaptive compensation of local illumination mismatches between frames of the multiview video sequence is provided. The method may be performed using a correction parameter used to correct a change in illumination. The correction parameter may be computed based on at least one of a first estimate estDi,j, a second estimate estRi,j, a value Ri,j of a pixel of a reference block, and values TDk and TRk of restored pixels.

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.
