With the wide application of the areal structured light scanner, the triangulation of the area-structure point cloud become the main bottleneck of the process. Since a one-to-one relationship is maintained between the image pixel and the data point in the area-structure point cloud, the information of the image implicating the certain topology structure can be merged into the point cloud. In order...
As we all know that the precision of data, which get from the measure part of the control system in modern industry, makes obvious influence in the whole system. High precision is always the key issue in the target recognition and location. The image measurement technology is one of the important branches. Depend on the research a new subpixel location method based on genetic algorithm (GA) is proposed...
A novel graphical model based on inhomogeneous Markov random field and Dirichlet process mixture is proposed to address the problems encountered by hidden Markov random field. It incorporates the local and global scale information. A sampling method is also devised based on Gibbs sampler. The model is investigated in the context of image segmentation and the performance is evaluated.
