摘要: 本文提出的定性描述图表示方法能在无模型指导的情况下有效地实现遮挡物体的分离, 并将识别过程转化为图或子图同构的问题,还提出了用"提纯"与"搜索"相结合的递归过程来 判定图或子图同构.实验证明了该方法的有效性和稳定性.Abstract: In this paper, a new 3D object qualitative representation called Qualitative Description Graph (QDG) is presented. This symbolic rep esentation can separate effectively the objects with occlusion and simplify greatly the identi ication of Objects in complex scenes. To improve the recognition efficiency, a recursive scheme integrating 'purifying' with 'searching' is proposed. Several experiments show that this approach is effective, robust and efficient.
