This paper presents a novel shape representation approach, Finite Element Skeleton (FES), based on studies of planar shape analysis from the perspective of Finite Element Method (FEM). First, we derive the shape contour of an object in image with edge detection approach. Then, the approach builds connections of all pixels on the shape contour with the inner center point of the shape, and models these...
This paper presents a novel shape representation approach based on Finite Element Region (FER). We assume an image blob can be treated as a mesh model that consists of a finite number of deformable quadrilateral pixel elements. These elements connecting side by side form an approximate physical model of the surface of real object. By employing Finite Element Method (FEM), the model's natural frequency...
In this paper, an electromagnetic tracking method that uses two rotating orthogonal coils is proposed. Two cross-shaped coils can rotate together and be driven in sequence to generate a magnetic field. One of the rotating orthogonal coils is used to track the position of the three-axis sensor and the other is to help solve the orientation of the sensor. As rotation can provide a geometrical relationship...
The particle laden flow over backward facing step is a typical flow for fluid machines. In order to simulating the two-phase flow in the flow, an anisotropic PDF model of particle proposed by author was employed. The standard k-e model was solved to gain the gas flow with finite volume method, and the anisotropic PDF model was calculated by a Finite Analytic/Monte Carlo Method. It is shown that the...
