dialect

Autonomous mobile robot navigation using fish-eye lenses,w passages and makes turns at the end of corridors. Fish-eye lenses are used to provide a large field of view, which helps in imaging objects close to the robot. The system is implemented and tested in a structured environment at our laboratory. Results from the robot navigation in real environments are presented.

不理會(huì)

Interactive particle tracing algorithm for unstructured grids,n efficient heuristic searching method to find the cell which contains the moving particle‘s new position. By using this efficient searching method, the presented algorithm allow an interactive investigation of complex vector data sets organized on unstructured grids.

性滿(mǎn)足

,GEOFF — A geometrical editor for fold formation,oidal function. In contrast with techniques which are based on the physical properties of the material, the technique is fast and yet produces visually acceptable results. The technique has been incorporated within the GEOFF interactive editor which allows the user considerable control over fold generation.

雜役

Simplification of polygonal surface with attributes,(2) dealing with geometric and nongeometric feature lines on the surface; A concept of semicircle criteria is proposed, that takes not only geometric features but attributes of the polygonal surfaces into account. Comparing with previous work, our method is more general, practical and flexible to complex objects. Several examples are demonstrated.

NEX

An object-oriented architecture for Chinese character composition,nd intermediate arguments which require a lot of human effort and knowledge. We illustrate an . to digitization of Chinese character glyphs (which we have implemented in Postscript), in which all intermediate subprocesses and arguments are hidden from the user, generating the characters in a black-box process.

Barrister

3D model-based video coding: Computer vision meets computer graphics,s used as an example. In this system, a generic 3D face model is used for both facial motion analysis and expression synthesis. The motion trajectories of the feature points are derived using computer vision techniques and computer graphics techniques are used to reconstruct the original motions usi

演繹

Autonomous mobile robot navigation using fish-eye lenses,mates the three-dimensional (3D) position of significant features in the environment, and by estimating its relative position, navigates through narrow passages and makes turns at the end of corridors. Fish-eye lenses are used to provide a large field of view, which helps in imaging objects close to

HAIL

High-performance tracking system,formance system with no special-purpose hardware. We consider image brightness and contrast changes in the tracking system which haven‘t been treated before. We find the decoupled system outperforms the usual coupled system. We perform this calculation at multiple levels of resolution, leading to an

藐視

A 3D predictive visual tracker for tracking multiple moving objects with a stereo vision system, different common-motion clusters and then predicts the motion of each cluster with Kalman filters. The 3D features are computed from a sequence of stereo images by combining two 2D temporal matching modules and one stereo correspondence module. To partition the 3D features into different common-mot
