This paper proposes an optimal path planning algorithm incorporating a global and local search mechanism for mobile robots. The global path planning is based on Voronoi graph to establish a backbone path for the map with significantly reduced nodes for the original grid map. With the use of the backbone path, the D* algorithm is adopted to determine a shortest path between the starting and end points...
Several common used image mosaics algorithms are analyzed and compared and new algorithm based on feature points matching is presented, in which stitch points is determined through finding corresponding feature points of two images and its matching position is determined; Image mosaics are accomplished through fusing process in overlapping area and experiment is carried out in order to test the algorithm...
