Abstract
A method of encoding an image pair (L,R) corresponding with two views of a multi-view signal, the method comprising generating a first combined image (LeRo) based on a first low pass filtered version of a first image of the image pair and a first low-pass filtered version of the second image of the image pair, generating a base-layer (LR-bas) by encoding the first combined image (LeRo), generating first and second disparity based predictors (LpredD,RpredD) and respectively associated first and second block-based displacement vectors (LHvec,RHvec) associated with the image information encoded in the base layer (LeRo′), the first and second block-based displacement vectors (LHvec,RHvec) being generated using disparity information present in the first and second images (L,R), the image information encoded in the base-layer (LeRo′) and the respective first and second images (L,R), generating an enhancement-layer (LR-enh; L-enh,R-enh) by encoding the first and second images (L,R) using the first and second disparity based predictors (LpredD, RpredD).
