This paper proposed a novel 3D face recognition algorithm using multi-level multi-feature fusions. A new face representation method named average edge image is proposed in addition to traditional ones such as maximal principal curvature image and range image. In the matching process stage, a new weight calculation algorithm based on the sum rule is presented for feature fusion and match score fusion...
Using the implicit conic to fit the given data points is an important problem in the fields of geometric modeling and numerical calculation. If the implicit conic is constructed by minimizing the algebraic distance, the selection of the coordinate system and the setting of the constraint are the two key issues that will affect the approximation accuracy heavily. This paper discusses the problems that...
A novel blind robust 3D mesh object watermarking method is proposed. Firstly, we choose the prongs of the mesh; secondly, to suppose that the prongs are the centers of the circle and the length we choose is the radius, we can get the areas which could be watermarked; and then, with the sphere coordinate, we will get the distance from the object center to the vertices, and perform DFT on the sphere...
A new method for volume visualization of CT images is presented. The new method uses the information that the given set of CT images is taken from an original volumetric function. The new method first computes the fitting points of the original function with data mining technique, then the fitting points are used to construct 3D model by MC algorithm. The constructed 3D model by the new method has...
