In this paper, we propose a new numerical method for solution of Urysohn two dimensional mixed Volterra-Fredholm integral equations of the second kind on a non-rectangular domain. The method approximates the solution by the discrete collocation method based on inverse multiquadric radial basis functions (RBFs) constructed on a set of disordered data. The method is a meshless method, because it ...

This paper develops a method for generating smooth trajectories for a moving rigid body with specified boundary conditions. Our method involves two key steps: 1) the generation of optimal trajectories in ( ), a subgroup of the affine group in IR and 2) the projection of the trajectories onto (3), the Lie group of rigid body displacements. The overall procedure is invariant with respect to both ...

In this paper, we proposed the distribution of mesh normal vector direction as a feature descriptor of a 3D model. A normal vector shows the entire shape of a model well. The distribution of normal vectors was sampled in proportion to each polygon's area so that the information on the surface with less surface area may be less reflected on composing a feature descriptor in order to enhance retr...

According to realized Batik Renderings, we presented an algorithm for creating ice crack effects as found in Batik wax painting and Batik techniques. This method is based on Interpolation Subdivisions algorithm, which can produce crackle effects similar to the natural texture generated in the batik handcraft. In this method, the natural distribution of ice crack is created by Random distributio...

The quotient from starting point divided by total parameter corresponding this point. researchers calculated optimum combination with help particle swarm optimization algorithm. computation aims find shortest curve. simulated strain data pla...

An iterative method based on the block matching collaborative filtering is proposed for image interpolation. Unlike the conventional interpolation methods, the proposed method first utilizes the wavelet-based linear interpolation method to generate an initial estimate of the original image. Then the observation constraint provided by the given low-resolution image is enforced on the estimate to...
