System and method for compressing and decompressing images using block-based compression format

Disclosed herein includes a system, a method, and a device for compressing image data. The device includes one or more processors, coupled to memory, configured to identify a plurality of sub-blocks of a block of image data including a first sub-block and a second sub-block. The one or more processors are configured to identify a first data characteristic of data of the first sub-block and a second data characteristic of data of the second sub-block, determine a first compression technique based at least on the first data characteristic of the first sub-block, determine a second compression technique based at least on the second data characteristic of the second sub-block, and compress the first sub-block using the first compression technique and the second sub-block using the second compression technique.
