A Mine Intersection Recognition Method Based on Geometric Invariant Point Detection Using 3D Point Cloud

RA-L 2022

In large-scale underground mines and mine-like deep urban canyons, intersections are crucial geometry structures. Accurate recognition of intersections is of great importance to improve localization precision for Unmanned Aerial Vehicles(UAVs) and Unmanned Ground Vehicles(UGVs). Currently, tradition

Abnormal event detection based on sparse reconstruction in crowded scenes

ICASSP 2016accepted

In this paper, we propose an algorithm of abnormal event detection in crowded scenes using sparse representation over the bases of normal motion feature descriptors. To construct an over-complete dictionary, we extract the histogram of maximal optical flow projection (HMOFP) feature from a set of no…
