Abstract

A novel technique for visually lossless medical image compression is presented Visually lossless compression is defined as removing visually insignificant information without evoking any degradation in image quality, through the suppression of visual distortions. An advanced perceptual distortion metric is adapted into the JPEG 2000 coding framework, whilst maintaining bit-stream compliance. Current simulation results have shown superior compression gains over that of the state of the art JPEG-LS and JPEG 2000 Lossless coders, without any visible distortions.

JPEG 2000医学图像的视觉无损自适应压缩

提出了一种新的医学图像视觉无损压缩技术。视觉无损压缩的定义是通过抑制视觉失真，在不引起图像质量下降的情况下去除视觉上不重要的信息。JPEG 2000编码框架采用了一种先进的感知失真度量，同时保持了比特流的遵从性。目前的模拟结果显示，与最先进的JPEG- ls和JPEG 2000无损编码器相比，压缩效果更好，没有任何明显的失真。
