| 摘要: |
| 基于图象内容的查询是根据图象实体(或区域)的颜色、形状、纹理、空间关系等特征属性来查询图象.它把图象处理、图象识别、图象数据库3个领域的技术成果结合起来,是一个有前途的发展方向.本文所作的工作是研究和实现根据图象实体(或区域)的形状来查询图象,内容包括：(1) 人对于形状的认知过程；(2) 表征形状的特征量集合；(3) 一种快速有效的图象匹配算法；(4) 原型系统Photo Engine. |

| Abstract: |
| QBIC (query by image content) is a method to query image by characteristics of the object (or region) of the image, which include color, shape texture and spatial relations. This new research project combines technique of IP (image process), IR (image recognition) and IDB, is a very prospecting domain. The authors deal with the investigation and realization of querying images by the shape of image objects(or region) in this paper, which includes: (1) the cognitive process of shape; (2) a set of characteristic to describe shape of image object; (3) an efficient match algorithm for image querying; (4) a prototype system for querying image by the shape of image objects, which named Photo Engine. |
| Key words: Shape, query by image content, image database, intra-angle. |
