A new spline method has been introduced. It is a generalization of the Ballpsilas cubic spline method and also serves as an affective alternate to the weighted Nu-splines. The generated spline curves have second order geometric continuity similar to those of weighted Nu-splines. In comparison with the existing techniques, the degree of the spline method is ideally three and the domain of the shape...
A new technique for the reconstruction of a smooth surface from a set of 3D data points is presented. The reconstructed surface is represented by an everywhere C1-continuous subdivision surface which interpolates all the given data points. The new technique consists of two major steps. First, an efficient surface reconstruction method is applied to produce a polyhedral approximation to the given data...
This paper presents a vector representation for polyhedra. Unlike coordinate representations, vector representations do not require fixing the polyhedra in a coordinate space to derive various properties or carry out various processes. The paper shows how the representation of primitive polyhedra can be used in a cellular construction of complex polyhedra through the gluing of counteractive faces...
As an important task in image processing, image registration has applications in medical analysis, remote sensing and computer vision etc.. However, since images taken by different sensors, automatic image registration, especially automatic feature matching, is difficult. Depending on the fact that the distortion between those images is near affine transformation, affine model is selected as the coarse...
