This paper presents a modified Iterative Closest Point (ICP) algorithm based on a suitable selection of initial points and local optical flow to speed up registration of static scenes with high accuracy. The biggest disadvantages of using standard ICP algorithm are appropriate initialization and effective matching point step in each iteration. In the proposed modification we deal with these problems...
The paper is concerned with the analytical aspects of the structural optimization problems for elastic bodies in the unilateral contact with a given friction. The contact phenomenon is governed by the second order elliptic variational inequality. The aim of the topology optimization problem is to find such material density distribution function in a domain occupied by the body to minimize its normal...
Topology optimization of bodies in unilateral contact with a given friction is considered in the paper. The contact phenomenon is governed by the second order elliptic variational inequality. The aim of this optimization problem is to find such distribution of the material density function to minimize the normal contact stress. The original optimization problem is reformulated in terms of Cahn-Hilliard...
The paper deals with the application of Lucas-Kanade optical flow algorithm to develop an augmented reality (AR) system. Merging of a live view of the physical real world with context-related computer-rendered images to create a mixed image is a challenging problem. A virtual object has to be located in the correct pose and position in real time and perspective. Besides the occlusion problem need...
The paper is concerned with the topology optimization of bodies in unilateral contact with given friction. The contact phenomenon is governed by the second order elliptic variational inequality. The aim of the optimization problem is to find such distribution of the material density function to minimize the normal contact stress. The phase field approach is used to analyze and solve numerically this...
The combined level set and phase field rather than classical level set approach is used in the paper to analyze and solve numerically the topology optimization problem for system governed by the variational inequalities. Classical level set method allows to evolve a given sharp interface but is not capable to generate holes unless the topological derivative is used. The phase field method indicates...
