|摘要:||This article presents a compression method to encode a 2D-gel image by using hybrid lossless and lossy techniques. In this method, areas containing protein spots are encoded using lossless method while the background is encoded using the lossy method. A 2D-gel image usually covers a large portion of the background in which has colors that are close to white. The VQ codebook-generating approach gives more codewords to describe the background: consequently, the proposed method can nearly precisely depict the background of the 2D-gel image and exactly record protein spots without any losses. Therefore, it can provide a high compression ratio. Image compressed by this method can nearly be lossless reconstructed. The experimental results show that the compression ratio is significantly improved with acceptable image quality compared to the JPEG-LS method. (C) 2006 Wiley Periodicals, Inc.|
