Feature detection and display are the essential goals of the visualization process. Most visualization software achieves these goals by mapping properties of sampled intensity values and their derivatives to color and opacity. In this work, we propose to explicitly study the local frequency distribution of intensity values in broader neighborhoods centered around each voxel. We have found frequency...
Bone drilling interaction is an important method of reducing the over prominent bone areas of the mandibular angle in cosmetic facial contour surgeries. A new haptic bone drilling interaction model based on Impulse Theorem and Coulomb Law is proposed in this paper, and a hybrid mandible bone reduction surgery training system is also developed with visual and haptic feedbacks. Experimental results...
