摘要

将基于背景亮度的空间域感知模型与无损压缩框架相结合，去除视觉冗余信息。将块匹配应用于医学图像中存在的解剖对称性，以去除切片内和切片间的相关性。得到的结果表明，与无损压缩技术相比，压缩效果更好，而视觉质量没有任何下降。

Symmetry based perceptually lossless compression of 3D medical images in spatial domain

A perceptual model developed in spatial domain based on background luminance is combined with lossless compression frame work to remove visually redundant information. Block matching is applied on anatomical symmetry present in medical images to remove intra slice and inter slice correlations. The obtained results show better compression gains against lossless compression techniques, without any degradation in visual quality.
