Coding method of image information

摘要: A coding method of a binary Markov information source comprises the steps providing range on number line from 0 to 1 which corresponds an output symbol sequence source, and performing data compression by expressing position corresponding sequence. The present further includes normalization keep desired calculation accuracy expanding mapping range, means multiple power 2, when becomes below 0.5 line; allocating predetermined for less probable symbols LPS proportional its normal occurrence probability; remaining more MPS; reassigning half portion where allocated is than 0.5, 0.5.
