Method For Imaging Coding By Rate-Distortion Adaptive Zero-Tree-Based Residual Vector Quantization And System For Effecting Same
US Patent:
7437010, Oct 14, 2008
Filed:
Sep 1, 2006
Appl. No.:
11/515227
Inventors:
Scott E. Budge - Logan UT, US
Qun Gu - San Jose CA, US
Qun Gu - San Jose CA, US
Assignee:
Utah State University - North Logan UT
International Classification:
G06K 9/46
US Classification:
382239, 382240
Abstract:
Methods and systems for encoding, transmitting and decoding digital images by rate-distortion adaptive zerotree-based residual vector quantization are disclosed. A method of the invention includes receiving a digital image, transforming the digital image into the wavelet domain generating a pyramid hierarchy, losslessly encoding a top LL subband from the pyramid hierarchy, encoding other subbands by vector quantization based on a zerotree insignificance prediction, generating an encoded image from the lossless encoding and vector quantization encoding, transmitting the encoded image along a communications channel, receiving the encoded image transmitted along the communications channel, reconstructing a zerotree from the encoded image, vector quantization decoding subbands from the encoded image other than a top LL subband, losslessly decoding the top LL subband from the encoded image, reverse wavelet transforming the top LL subband and the vector quantization decoded subbands and outputting a decoded image.
