ABSTRACT:
A computer system includes a memory and a processor. The memory stores a program to cause the processor to provide error data that indicate motion in an image. The processor represent each error signal as a collection of ordered bits, and the processor codes the bits of each order to indicate zerotree roots that are associated with the order.
