基于子带分解的对角线性插值与IFS相结合的图像编码方法
A New Method of Image Encoding Based on Subband Dividing and Combined IFS with Diagonal Linear Interpolation
【摘要】 提出一种基于Walsh四子带分解的、把Z形扫描、对角线性插值与基于迭代函数系统(IFS)的四叉树分形编码相结合的混合图像压缩新方法.实验结果表明,与基本的自动分形图像压缩方法相比,在基本保持重建图像质量的前提下,运算时间减少而压缩比显著提高
【Abstract】 A new image compression encoding method based on Walsh quadsubband dividing is presented by combing diagonal quadratic interpolation scanned as Z shape and iterated function system theories.Compared to basic automatic fractal coding method,computation time is saved and compression ratio is improved remarkable with no apparent depression on the quality of the reconstructed image.
