In the real scene, the captured images come from the 3-D world. 3-D corner as a novel invariant feature is important for the image matching and the object detection, while automatically discriminating 3-D corners from ordinary corners is difficult. A novel method for 3-D corner detection is proposed based on the image graph grammar, and it can detect the 3-D features of corners to some extent. Experimental results show that the method is valid and the 3-D corner is useful for image matching.展开更多

The current Chinese realistic oil painting is the product of local culture. The construction of Chinese oil paintings doesn＇t follow modem art, and it has its own soil and space of survival and development. It becomes the mainstream in the art pattern. In practical construction, it presents the characteristics that technical level develops towards simplification and reinforcement, the function of lyric ideogram of paintings and graphic description becomes weak, the real transformation of three-dimensional space is transferred to reconstruction of two degree and a half space and the pursuit for language form constitution relation of paintings. And it presents strong symbolization feature.展开更多
