摘要
提出了一种基于非线性变换的分形图像压缩编码方法。证明了引入的非线性变换满足压缩迭代映射理论。模拟实验的结果表明 ,与传统的分形图像压缩编码方法相比 ,压缩比和峰值信噪比均有所改善。
In this paper,a fractal image coding approach based on non linear transforms is proposed The non linear transforms satisfy a theory of contractive iterated image transformations Simulation results show that this proposed approach can improve bit rate and peak signal noise ratio(PSNR)by comparing with a traditional fractal image coding method
