In other words, it is necessary for Ti encoder of EBCOT to encode each bit plane of code blocks in the image according to context-based arithmetic encoder. There is no doubt that this operation is time-consuming and requires enormous computation volumes.
Algorithm Binary Coder (Figure 17) details the operation of a binary arithmetic encoder and decoder; [C.sub.0] and [c.sub.1] are assumed to be the frequencies of symbols zero and one respectively, and bit is the bit to be actually transmitted.
