Reversible embedded wavelet transform system implementation

摘要

A method for performing compression and/or decompression using reversible wavelet transformation is described. In one embodiment, the present invention comprises a system having a buffer, a reversible wavelet transform unit, and a coder. The wavelet transform unit has an input coupled to the buffer to perform a wavelet transform on pixels stored therein and to generate coefficients at an output. The coder is coupled to the wavelet transform unit to code the transformed pixels received from the buffer.
