In computerized image and graphic applications, texture mapping is one of the most commonly used methods to improve the realism or to enhance the visual effect of object rendering without too much increase in computational complexity. The conventional method usually has to transfer three-dimensional (3D) object to the polygonal structure, and is(More)
Semi-boundary (SB) data structure is a compact voxel surface representation of the structure from the medical images. It represents only the boundary of the extracted structure and only an opaque object boundary involved in a 3D dataset can be visualized. Its computational complexity is in proportion to the number of SB voxels. In this paper, we propose(More)
Petri net is a mathematical modeling language used to describe a system graphically. It is a strong language that can be used to represent parallel or concurrent activities in a system. With a Petri net tool, users can view the overall system graphically and edit it with the editor. A Petri net tool can also be used to analyze the performance of the system,(More)
About twenty five percent of people have the typical phenomenon, i.e. a specific feeling propagating along the channel course during the application of needling or other stimuli on Jing acupoint. These characteristics are named marked PSC. About seventy five percent of people with no prominent propagated sensation. We concerned about how to change the(More)
