In this work, we propose an efficient and accurate partial shape matching algorithm to recognize 3D teeth for human identification. Given the ante-mortem and post-mortem teeth models which were taken from patients using a laser scanner, we first extract a series of stable and consistent feature ...

1、可以看一下主流的商业机器视觉库,比如Halcon,康耐视的VisionPro及它的PatMax专利算法,OpenVision里的Match和Find模块,这些商业库里的匹配算法都占有很高的篇幅和重要性,而它们的鲁棒性也不是一般算法可以比拟的。 再推荐一本书,《机器视觉算法及应用 Machine vision algorithm and Application》,是Halcon的资深研发人...

matching algorithm also enables the seam tracking system to automatically localize the starting and finishing point of the weld seam. A FIFO based queue was defined and implemented to tackle the lag distance problem between theheat sourceand the vision sensor. The tracking algorithm, along with the...

ContextShapes does rigid-body protein docking. It uses a novel contextshapes data structure to represent local surface regions/shapes on the protein. All critical points on both the receptor and ligand are represented via context shapes, and the best docking is found via pair-wise matching. ...
The key idea is based on keeping track of all optimal solutions, which may be more than one due to symmetry especially at coarse levels, throughout denser levels of the shape matching process. We compare the resulting dense correspondence algorithm with state-of-the-art techniques over several ...
