Google patents video compression trick using edge pixels
This filing describes a method for compressing video data by refining how motion is calculated for small blocks of pixels. It filters out certain surrounding pixels that do not meet specific conditions before using the remaining ones to improve the accuracy of the motion data.
In the filing’s own words
Coding a current block includes determining that the current block is coded using a template matching mode. In the template matching mode, an initial motion vector for the current block is refined based on template peripheral pixels that are at least a subset of peripheral pixels to the current block. The template peripheral pixels are obtained by excluding pixels of the peripheral pixels that do not meet a template-inclusion condition. A motion vector for the current block is obtained based on a refinement operation that uses the template peripheral pixels and does not use the excluded peripheral pixels. The current block is then coded based on the motion vector.
What exactly they claim (claim 1)
1. A method for coding a current block, comprising: determining that the current block is coded using a template matching mode, wherein in the template matching mode an initial motion vector for the current block is refined based on template peripheral pixels that are at least a subset of peripheral pixels to the current block; excluding, to obtain the template peripheral pixels, pixels of the peripheral pixels that do not meet a template-inclusion condition; obtaining a motion vector for the current block based on a refinement operation that uses the template peripheral pixels and does not use the excluded peripheral pixels; and coding the current block based on the motion vector.
