Lossless and Near-Lossless color Image coding Using Edge Adap0tive Quantization

摘要

This paper proposes a unified coding algorithm for the losslessand Near-lossless compression of still color images. The proposedunifed color image coding scheme can control the Peak Signal-to-NoiseRatio (PSNR) of the reconstructed image While the level of distortionon the RGB plane is suppressed to Within a preset magnitude.
