The Recovery of a motion-blurred image is an important ill-posed inverse problem. The goal of the present work is to provide a probabilistic method for the detection of motion parameters based on the geometrical characteristic of the Fourier spectrum. To achieve this goal, the method first detects the maximum meaningful parallel alignments in the frequency domain of the blurred image using the Helmholtz...
A new hybrid particle swarm optimization (HPSO) algorithm which is based on particle swarm optimization algorithm and simulated annealing algorithm is proposed in this paper for solving multiple capacitated vehicle routing problem. The basic scheme consists in Particle swarm optimization with time-varying parameters and simulated annealing with memory and tempering features. Results from the computational...
Under the target of maximum number of vehicles in a stage plan, the model of dynamic wagon-flow allocating under the uncertain condition can be built. The improved approximate nondeterministic tree search (ANTS) algorithm whose parameter ?? fixed by chaos sequence generator will be introduced by means of defining the possibility break up set, waiting set and choice set to mapping dynamic wagon-flow...
Texture synthesis is used to render high quality textures on surfaces, and has been widely recognized as an important research topic in surface rendering. To overcome the low efficiency of previous methods, we present a fast algorithm to synthesize texture on surfaces. First, the surfaces are segmented into a series of mapping areas and synthesis areas using constraints of normal vector error. Then...
This paper introduces the radio frequency identification (RFID) technology and the RFID anti-collision algorithms. The application mode of the RFID dynamic grouping anti-collision algorithm based on fuzzy c-means (FCM) clustering theory is stated. The selection of RFID tag grouping indexes is presented. The steps of the proposed anti-collision algorithm are developed. The simulation results show the...
