摘要
分形图像编码中,最大的困难是搜索与值域块相匹配的定义域块,由于定义域块数量巨大,搜索很费时,本文从减少搜索块的数目和缩小搜索块的范围出发,提出多分辨率编码,从两个方面减小编码时间。为了减小对图像质量的影响,在抽样时采用双线性插值和双三次插值,以减小方块效应。
The difficulty in fractal image encoding is great magnitude of the domain blocks which must be sought.It takes much time to find the best block which matches the range block.In this thesis,we use interpolation and multi-resolution to reduce the blocks that need seeking.In order to keep th e image from being impacted greatly,we use bilinear and bicubic interpolation first.
