We present a new user interface for the virtual sculpting system. In our system, the user operates a chisel with a pressure sensitive pen to carve a workpiece in the virtual space. The user can control the depth of carving and the angle of the virtual chisel to the surface of the workpiece dynamically like the real wood carving.
In this paper, we propose a new recognition method of lung nodules from X-ray CT images using 3D Markov random field(MRF) models. Pathological shadow candidates are detected by a mathematical morphology filter, and volume of interest(VOI) areas which include the shadow candidates are extracted. The probabilities of the hypotheses that the VOI areas come(More)
