Region Based Coding of Volume Data using Finite Mixture Model

The region-based coding of the volume data is proposed in the present paper. Since the volume data is the three dimensional one, the visualization method is needed to display it. The region segmentation is indispensable to visualize the desired portions only. In the proposed method, the region segmentation result is utilized to code the volume data; the contours and the colors of the regions are coded. The nite mixture model is used to segment the data, and the parameters of this model is used to represent the opacity needed in the volume rendering. The preliminary results of the experiments for the CT data are shown.
