Originální abstrakt

A new method for pre-processing of computer tomography (CT) images is proposed in the paper. The method is based on down-sampling of histogram of an intensity CT image. This helps to overcome a disadvantage of vommon segmentation algorithms - low contrast and blurring of iteresting objects in CT images. Inaccuracy resulted from the down-sampling procedure is improved using a Markov random field model which takes into account geometrical constraints of the processed image.
