Abstract

To compress medical images in a lossy way that preserves their diagnostic value, the authors have combined lossless compression techniques with a fractal image compression method using two kinds of iterated function systems: partitioned, and condensation-model. The algorithm appears to yield a compression ratio of about 15:1 without perceptible degradation.<>

基于分形模型的医学图像压缩
为了以有损的方式压缩医学图像,保留其诊断价值,作者将无损压缩技术与分形图像压缩方法结合起来,使用两种迭代函数系统:分区和凝聚模型。该算法似乎产生了约15:1的压缩比,而没有明显的退化。
