Title: ADAPTATION OF SCAN ORDER FOR ENTROPY CODING
Abstract:
Systems and methods are disclosed for adapting scan order for entropy coding. For example, methods may include partitioning a block of video data into a plurality of groups of elements, decoding, using an entropy decoder, data from an encoded bitstream to obtain, using a first scan order, elements of a first group from the plurality of groups of elements, determining, based on the elements of the first group, a second scan order for a second group from the plurality of groups of elements, and decoding, using the entropy decoder, data from the encoded bitstream to obtain, using the second scan order, elements of the second group from the plurality of groups of elements.
