Scan-Based Quality Control For Jpeg2000 Using R-D Models
Year: 2002
Type: article
Abstract: JPEG 2000 compression of very large images (e.g. medical imaging, microscopy, satellite images, photography) requires tiling processing. Tiling processing results in border artifacts. Scan-based wavelet transform avoids these artifacts. However scan-based methods using rate control result in poor local quality control. Most of applications require quality control image coding with- out any real time rate constraint (e.g. off-line compression for storage or for broadcasting over IP, ADSL ...). Therefore, we propose a new scan-based wavelet transform compression algorithm based on quality control for JPEG 2000-like codecs. The method proposed in this paper ensures accurate local quality control and can provide a global rate-distortion improvement up to 1.7 dB in PSNR comparatively to a rate control procedure.
