针对图像感知编码算法的编解码程序代码，特别是分形图像压缩-Perceptual coding algorithm for encoding and decoding program code, in particular, fractal image compression

The efficiency of perceptual coding in compressing color images relies on the estimation of perceptual redundancy. In this paper, a color image coder is proposed for perceptually lossless image compression which shapes the coding error as a p

In this paper we propose a watermarking system that uses the biorthogonal discrete wavelet transform, DWT and the message is encoded before embedding. The proposed watermarking method is very simple, implying four steps: turbo coding of
