This work describes the problem of medical images segmentation. The goal of this work was to develop a new semi-automatic segmentation method that could process medical images. In this work a new segmentation method is proposed. It uses a combination of three segmentation algorithms and two image enhancement methods, of which two histogram-based segmentation algorithms and one image enhancement algorithm were developed by the authors. This work describes the method and developed algorithms. The proposed method is semi-automatic. It automatically enhances the image and divides the image into segments. For now, the choice of segment that contains the pathology zone is user-dependant, but the proposed method makes the search for pathology zones easier. The proposed method was tested on medical images, and after the study of results, the conclusion was made, that the method can be used as an extra tool for image analysis, to make the diagnostics of medical image easier.
