A Direct Segmentation Algorithm of Medical Volume Data Based on Fuzzy Transition

3D direct volume segmentation is a nodus and one of research hotspots in 3D medical data field processing. Through the analysis of physical properties of the medical data field, a direct segmentation algorithm of medical volume data based on fuzzy transition is put forward. Firstly, the existence of transitional regions and the feasibility of fuzzy segmentation in the medical data field are demonstrated. Secondly, middle region between-class that is difficult to distinguish is segmented into transitional regions so as to avoid either-or rigid segmentation in common segmentation algorithm. Finally, the experimental results shows that the algorithm not only decreases the segmentation difficulties of medical data field, but also satisfies the non-rigid segmentation requirements for the following rendering and at the same improves the anti-interference capability of segmentation.
