Abstract

 

The method of compression without losses based on octree representation in application to three-dimensional biomedical images was considered. The modification of this method that implements compression with losses using noises pre-filtering was suggested.  It is shown that this method is better in quality of compression than methods of two-dimensional compression with losses or without them (PNG and JPEG) applied to three-dimensional images layer-by-layer.


Keywords: image compression, biomedicine, octree.
