Google patents video compression shortcut for small image blocks
This filing describes a method for compressing video data by simplifying how small sections of an image are processed. When a block of pixels is small enough, the system automatically uses a standard mathematical formula instead of calculating a new one for each section.
In the filing’s own words
A device includes a memory and a processor. The processor is configured to execute instructions stored in the memory to determine whether a size of a transform block is below a predefined block size. In response to determining that the size is not below the predefined block size and that one of a width or a height of the transform block is equal to a minimum threshold transform dimension size, a default transform type is selected, as a transform type, for the one of the width or the height of the transform block that is equal to the minimum threshold transform dimension size. The transform type is then applied to the transform block.
What exactly they claim (claim 1)
1. A device, comprising: a memory; and a processor, the processor configured to execute instructions stored in the memory to: determine whether a size of a transform block is below a predefined block size; in response to determining that the size is not below the predefined block size and that one of a width or a height of the transform block is equal to a minimum threshold transform dimension size, select, as a transform type, a default transform type for the one of the width or the height of the transform block that is equal to the minimum threshold transform dimension size; and apply the transform type to the transform block.
