| Abstract: |
This paper proposes a novel lossless coding scheme for color still images. The scheme employs a block-adaptive inter-color prediction technique to remove both spatial and spectral redundancy in RGB color signals. The resulting prediction errors are encoded using a context-adaptive arithmetic coding method. Several coding parameters which must be encoded as side information are iteratively optimized for each color signal. Experimental results show that the inter-color prediction technique provides better coding performance than a simple combination of reversible color transformation and intra-color prediction techniques. |
