Abstract
A computer system includes a memory and a processor. The memory stores a program to cause the processor to provide wavelet coefficients that indicate an image. The processor represent each wavelet coefficient 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.
Claims18
A method comprising:
- providing wavelet coefficients that indicate an image, the bits of each wavelet coefficient being associated with a different bit order so that each bit order is associated with one of the bits of each wavelet coefficient;
- expressing the wavelet coefficients in signed binary representation;
- determining whether a rate of coded bits exceed a predetermined bit rate;
- and
- generating the coded bits to indicate zerotree roots that are associated with the bit orders and regulating the generation based on whether the rate exceeds the predetermined bit rate.

An article comprising a storage medium readable by a processor-based system, the storage medium storing instructions to cause a processor to:
- provide wavelet coefficients that indicate an image, the bits of each wavelet coefficient being associated with a different bit order so that each bit order is associated with one of the bits of each wavelet coefficient;
- express the wavelet coefficients in signed binary representation;
- determine whether a rate of coded bits exceed a predetermined bit rate;
- and
- generate the coded bits to indicate zerotree roots that are associated with the bit orders and regulating the generation based on whether the rate exceeds the predetermined bit rate.
