1. The main applications are curve modeling and shape description.

2. In this paper, a method for objects shape description based on chain code and Fourier descriptor is proposed and its properties are explained and verified by experiments.

3. As the curvature is useful to enhance the shape description, the shape of the model can be preserved well after our simplification process.

4. Of many methods, straight-edge-line-based shape description is the best one not only because it is abstract sufficiently, but also because it provides abundant information.

4. try its best to gather and create good sentences.

5. Itconsists of a GORC physical data structure, detailed shape description and abstract description.

6. Geometric shape description is one of the main research topics in computer graphics, computer vision and pattern recognition.

7. An important feature of shape description is the contour curves of object. To improve the efficiency of recognition, dominant points are usually used to represent the contour.

8. Research on the boundary-based shape description method of the trademark image.

9. A novel method for performing point-feature correspondence based on the color and shape description is proposed in this paper.

10. Select the view, remembering that, aside from the view showing the characteristic shape of the object, there should be as many additional views are necessary to complete the shape description.

11. In order to improve the quality, this paper presents a two-stage residual spectral shape description model.
