Application of reversible denoising and lifting steps to DWT in lossless JPEG 2000 for improved bitrates
作者:
Highlights:
• Denoising is integrated with DWT lifting steps in lossless JPEG 2000.
• A heuristic is used for image-adaptive selection of denoising filters.
• Significant bitrate improvements are obtained for nonphotographic images.
• Consistently good performance is observed on images with impulse noise.
• Compression schemes with various bitrate-complexity tradeoffs are proposed.
