摘要
开发了一个基于草绘的三维物体检索的系统,该系统利用特征线条作为输入。为了客观评价,从与已有的物体数据库有关的个人用户那里搜集了大量查询草图。由于草图原来是与原始形状有着很大局部以及全局背离的一般抽象,因此,利用了"特征包"来处理由计算机产生的物体线图。
We develop a system for 3D object retrieval based on sketched feature lines as input.For objective evaluation,we collect a large number of query sketches from human users that are related to an existing data base of objects.The sketches turn out to be generally quite abstract with large local and global deviations from the original shape.Based on this observation,we decide to use a bag-of-features approach over computer generated line drawings of the objects.
