METHOD AND SYSTEM FOR ACHIEVING CODING GAINS IN WAVELET-BASED IMAGE CODECS |
| 摘要 |
<p>A method and system for coding and decoding RGB image. The RGB image component are converted into YUV components (10). One or more of the lower bit planes are eliminated (20). YUV components are transformed by forward wavelet (30). The codestream is decoded and transformed by inverse wavelet transform wavelet transform into YUV component (160). The bit-planes of YUV components are up-shifted (70). The up-shifted YUV are then converted into RGB component (80).</p> |
