摘要
采用了一种新的基于分形的图像压缩方法对一脑CT图像进行了图像压缩。结果表明 :压缩比为 45 .0 2 ,峰值信噪比PSNR为 2 7.5db ,运算时间为 0 .75h。利用分形实现图像数据压缩处理可以获得高的压缩比 ,压缩后能够保持信号与图像特征基本不变 ,有较广的应用前景。
An image compression based on fractal was used in a CT image compression.Experiments showed that compression ratio was 45.02, PSNR was 27.5db and computation time was 0.75 hour.The new method can get higher compression ratio、higher PSNR and quicker computation speed and the experimental results show that the algorithm is feasible.
