METHODS OF CODING, DECODING AND REPRESENTATION OF IMAGES OF HIGH DYNAMIC RANGE Russian patent published in 2019 - IPC H04N19/184 H04N19/36 

FIELD: calculating; counting.

SUBSTANCE: invention relates to decoding of digital images of HDR. Technical result consists in reducing undesirable artefacts when decoding HDR images and reducing the possibility of hash-conflicts. Method includes obtaining base layer data for a high dynamic range (HDR) image, obtaining a first checksum parameter, obtaining residual relationship data for HDR images.

EFFECT: calculating a second checksum parameter for the base layer data and comparing the first checksum parameters with the second checksum parameters.
