Creating a realistic three-dimensional human face model has been one of the most difficult problems in the fields of computer graphics and computer vision. A method witch to build three-dimensional human face model basic on a photo of two-dimensional single front face is proposed in this paper. Firstly, facial organ distribution is identified from the photo by face recognition. After that, the standard...
Based on computational geometry of the triangle, triangular mesh representation model of image is efficient to represent images, which has great use video communication, three-dimensional reconstruction and so on. Referring to the idea of contour extraction, characteristic points of image border can be extracted by use of polygon growing algorithm, Delaunay triangular mesh can be initialized with...
With the development of medical treatment, various kinds of medical images become more and more important. The traditional hierarchical structural image representation methods put too much emphasis upon the symmetry of segmentation, they are not the optimal image representation methods. DNAM-based multi-valued image presentation method has not only better compression ability but also has better reconstruction...
A quick online predictive parameter optimization guidance method for sub-orbital vehicle in reentry phase was developed in this paper to adapt the complicated reentry aero environment. First the aero characteristic of vehicle was analyzed. Base on the result of aero glide ability and attitude maneuver ability, a logical attack angle and bank angle model was introduced to suit for the reentry aero...
The method of multi targets evaluation and allocation for multi kill vehicle was present in this paper. Base on the information from targets Method of prediction impact point was adapted to get the impact point and remain flight time. Then fuzzy method was used to compute the threat coefficients of targets using these parameters. Target allocation model was built in space environment. Genetic algorithm...
Mobile SVG is adopted as the imaging standard of MMS by 3GPP - the partner of 3G. When generating mobile SVG on resource limited mobile devices, the memory space and computation capability become serious constrain which we should pay more attention. By analyzing the characteristics of mobile SVG basic shapes, this paper presents a uniform representation model based on path. Then this paper puts forward...
With the development of medical treatment, various kinds of medical images become more and more important. Most of them are multi-valued image. Although the hierarchical structural image representation methods have many merits, they put too much emphasis upon the symmetry of segmentation. Therefore, they are not the optimal image representation methods. With the concept of packing problem, a dNAM-based...
