ABSTRACT:
Methods and systems for compressing an image are described. A plurality of transformed and quantized values associated with a block of image data is accessed. The block corresponds to a position within the image. A count of the number of bits encoded during run-length encoding of the block is made. Run-length encoding of the block is concluded should the count reach a limit.
