Abstract:
Systems and methods are described for predicting a mode value of a block of an image. Mode values are received for a predetermined number of neighboring blocks of the image. Each mode value may within a predetermined range of integer values. Using a probability table, a probability of each mode value in the range of integers being selected may be computed. The probability table may have a first axis that includes every integer value within the range of integer values, and second axis that includes combinations of the neighboring blocks, each combination of the neighboring blocks representing a binary determination whether or not each neighboring block is equal to a corresponding integer value on the first axis. Based on the computed probabilities, a mode value for the block may be selected and coded by an entropy coder.
