With the increasing needs from a variety of real world applications like context retrieval and aid reading, scene text recognition is attracting more and more attention from the computer vision community. Scene text character (STC) recognition plays an important role in this task. However, recognition of STC is a challenging task due to a series of problems, like different illumination conditions,...
Binocular disparity is of vital importance in stereoscopic vision. It determines the depth magnitude and effects the impression formation when human watch three-dimensional things. However so far how binocular disparity activates the brain regions hasn't got consistent conclusions. So a fMRI(functional magnetic resonance imaging) experiment was designed to locate cortex areas related with stereoscopic...
A new dynamic 3D scene retrieval approach is proposed based on a novel dynamic Bayesian network (DBN) lightfield descriptor. To overcome the disadvantages of the existing 3D scene retrieval methods, we explore dynamic Bayesian network for building a new lightfield descriptor. Firstly, dynamic 3D object is put into lightfield, and many gray-views can be obtained along a sphere, and then features can...
A method of object detecting based on local contour learning and matching is proposed. Firstly, the representative images are obtained through unsupervised clustering to be as templates. The local contour information of template is extracted and generalized as the template feature, at the same time, codebook dictionary of local contour is built up. Secondly, based on codebook dictionary, using simple...
A scheme of segmentation based on low-level and high-level cues is presented. Firstly, image-pyramid is obtained based on segmentation by Weighted Aggregation (SWA), the suitable coarse pixel image is selected to be as low-level segmentation cues. Kernel principal component analysis (KPCA) is used for building the space of shape to represent shape prior knowledge. The coarse pixel image is expressed...
This paper analyzes systematically widespread problems about the most of bus stop boards existing in domestic ordinary, which include incomplete bus information in one area, lack of traffic information about the city and low humanity. In view of these problems,the paper proposes conceptual design of anew bus stop board on the basis of control ability and opening information. The conceptual design...
