Sažetak
Conduction of tele-3D-computer assisted operations as well as other telemedical procedures often requires highest possible quality of transmitted medical images and video. Unfortunately, those data types are always associated with large telecommunication and storage costs that sometimes prevent more frequent usage of such procedures. We present a novel algorithm for lossless compression of medical images that is extremely helpful in reducing the telecommunication and storage costs. The algorithm models the image properties around the current, unknown pixel and adjusts itself to the local image region. The main contribution of this work is the enhancement of the well known approach of predictor blends through highly adaptive determination of blending context on a pixel-by-pixel basis using classification technique. We will show that this approach is well suited for medical image data compression. Results obtained with proposed compression method on medical images are very encouraging, beating several well known lossless compression methods. Proposed predictor can also be used in other image processing applications such as segmentation and extraction of image regions.
