METHOD OF USING EDGE SHIFT Russian patent published in 2019 - IPC H04N19/86 H04N19/117 

FIELD: calculating; counting.

SUBSTANCE: invention relates to the computer equipment. Disclosed is a device for postprocessing a reconstructed image, wherein the device includes an unlocking filter for determining boundary strength for each edge of 4 samples, which is the prediction edge or conversion edge and lies on grid of 8 x 8 samples, determining whether unlocking filtering is applied on edge of 4 samples or not, using boundary strength and the boundary quantisation parameter, and filtering edge of 4 samples, if unblocking filtering is applied on edge of 4 samples; and unit of addition of sample adapted to selection for, if type of adaptive to sample shift to indicate edge offset, generation of edge index of current sample, generating an edge offset corresponding to the edge index of the current sample, and adding an edge offset to the current sample.

EFFECT: technical result consists in reduction of difference between initial samples and reconstructed samples.
