METHOD OF ENCODING/DECODING MULTI-VIEW VIDEO SEQUENCE BASED ON ADAPTIVE LOCAL ADJUSTMENT OF BRIGHTNESS OF KEY FRAMES WITHOUT TRANSMITTING ADDITIONAL PARAMETERS (VERSIONS)

摘要

FIELD: physics, computer engineering.;SUBSTANCE: invention relates to computer engineering and specifically to digital signal processing techniques. Disclosed is a method for adaptive local adjustment of change in brightness of a key frame for encoding a multi-view video sequence, in which a pixel value of the current encoded unit belonging to the encoded frame and a pixel value of the reference unit belonging to the key frame are obtained. The method further involves obtaining recovered, i.e. encoded and then decoded, pixel values that are neighbouring with respect to the current unit of the encoded frame, and pixel values that are neighbouring with respect to the reference unit of the key frame. Pixel differing from the overall set of recovered pixels are then excluded from consideration according to a predetermined criterion.;EFFECT: high encoding efficiency.;21 cl, 10 dwg
