Performance Evaluation of 3D Local Feature Descriptors [PDF]
, 2015 A number of 3D local feature descriptors have been proposed in literature. It is however, unclear which descriptors are more appropriate for a particular application. This paper compares nine popular local descriptors in the context of 3D shape retrieval, 3D object recognition, and 3D modeling.

Learning Local Feature Descriptor with Motion Attribute For Vision-based Localization [PDF]
2019 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2019 In recent years, camera-based localization has been widely used for robotic applications, and most proposed algorithms rely on local features extracted from recorded images. For better performance, the features used for open-loop localization are required to be short-term globally static, and the ones used for re-localization or loop closure detection ...
