Simulating the behavior of elastic objects is an important research in the field of virtual reality. Visual simulation of soft tissue deformation is the core part of the surgery simulation system. However, there is not a uniform deformable model. To choose a suitable model for surgery simulation, a classification of deformation models is offered in this paper. The deformable model can divide into...
This paper deals with the rendering issues of producing a realistic surgery simulation in real-time. In general, the visual fidelity of the simulator determines the degree of realism experienced by users. On top of the tissue, there is a mucous layer which is wet and semi-transparent. It significantly influences the surface appearance by reflecting and scattering incoming light rays. This paper describes...
Urinary sediment inspecting is that doctor counts the organic visible sediments in urinary and different sediments components so that we can know the status of kidney disease. In this system, we adopt the digital image microscope technology to observe directly the visible components which include RBC, WBC, Cast, Crystal etc in urinary sediment. The proposed method which uses the computer image recognition...
