METHOD OF SEARCHING FOR DISPLACEMENT VECTORS IN DYNAMIC IMAGES Russian patent published in 2013 - IPC H04N7/32 G06T7/20

Abstract RU 2487489 C2

FIELD: information technology.

SUBSTANCE: displacement vectors are searched for by searching for global displacement, breaking up the image into multiple layers of blocks, successive processing of the layers using various search schemes, using displacement vector prediction, as well as selecting displacement vectors based on efficiency of their further entropy coding.

EFFECT: quality improvement of efficiency of a video compressing system, especially at low bit losses, high output thereof.
