The impact of image information on compressibility and degradation in medical image compression

Medical Physics, 2006
The aim of the study was to demonstrate and critically discuss the influence of image information on compressibility and image degradation. The influence of image information on image compression was demonstrated on the axial computed tomography images of a head. The standard Joint Photographic Expert Group (JPEG) and JPEG 2000 compression methods were

HVS-based medical image compression

European Journal of Radiology, 2005
With the promotion and application of digital imaging technology in the medical domain, the amount of medical images has grown rapidly. However, the commonly used compression methods cannot acquire satisfying results.In this paper, according to the existed and stated experiments and conclusions, the lifting step approach is used for wavelet ...

Reversible intraframe compression of medical images

IEEE Transactions on Medical Imaging, 1988
The performance of several reversible, intraframe compression methods is compared by applying them to angiographic and magnetic resonance (MR) images. Reversible data compression involves two consecutive steps: decorrelation and coding. The result of the decorrelation step is presented in terms of entropy.
