The features are stable and discriminable. The invariants are semi-local rather than global, which promotes tolerance to occlusion. The considerable redundancy is possible for the object whose boundary has complex structure, which enhances the reliability of object recognition.

本方法提取特征不变量只需对待识别图像进行处理，不需要进行摄像机标定和目标空间姿态测量，特征不变量具有较好的稳定性和可分辨性，在目标被部分遮掩的情况下，仍然可能获得可靠的识别，另外，边界结构复杂的目标提供了冗余特征，增强了识别的可靠性。

No stent-related complications, such as graft occlusion, dislodgement, dissection, or endoleak, were observed in the perioperative period.

在围手术期没有诸如移植物血管闭塞、位置移动、切割及内瘘等支架相关的并发症。
