Abstract
Various examples are directed to methods and systems for compressing a binary mask. A computer device may determine that a frequency of a less frequent pixel value state of the binary mask is less than a threshold frequency and may select a block size corresponding to the threshold frequency. The computing device may determine a first run length number of pixel value blocks of the block size that are positioned consecutively in the binary mask sequence and that comprise a first pattern of pixel values and write the first run length number to a first compression sequence.
