Samsung patents video compression trick for small image blocks
Samsung has filed a patent for a method to compress video by grouping small sections of an image together. The system decides how to group these sections based on their shape and size to save data during transmission.
In the filing’s own words
An image encoding/decoding method of the present invention constructs a merge candidate list of a current block, derives motion information of the current block on the basis of the merge candidate list and a merge candidate index, and performs inter prediction on the current block on the basis of the derived motion information, wherein the merge candidate list can improve encoding/decoding efficiency by adaptively determining a plurality of merge candidates on the basis of the position or size of a merge estimation region (MER) to which the current block belongs.
What exactly they claim (claim 1)
1. An image decoding method, comprising: configuring a merge candidate list of a coding block; deriving motion information of the coding block based on the merge candidate list and a merge candidate index; and performing inter prediction of the coding block based on the derived motion information, wherein the merge candidate list includes a plurality of merge candidates, wherein, in response to a ratio of a width and a height of the coding block being less than a first threshold value and a number of samples belonging to the coding block being equal to a second threshold value, a plurality of partitions belonging to the coding block shares the merge candidate list and the merge candidate index is signaled, for each of the plurality of partitions, from a bitstream, and wherein the first threshold value and the second threshold value are pre-defined in a decoding apparatus and are different from each other, wherein the plurality of partitions is determined based on partition direction information.
