DOI: 10.1007/s11760-021-01854-0
Abstract: Frustum-based 3D detection methods suffer from the ignorance of a 2D detector for that the object will never be detected in point cloud if it is omitted by a 2D image proposal. In this work,… read more here.

DOI: 10.1109/jiot.2022.3231369
Abstract: Current 3-D object detection technology for autonomous driving usually cannot efficiently utilize local sensitive points. Meanwhile, contextual feature extracted from a object is not sufficient, which easily leads to deteriorated detection accuracy of the final… read more here.

DOI: 10.1177/14644207231173053
Abstract: In this research, thin-walled steel energy absorbers were investigated. The introduced structures absorb energy through the processes of inversion, folding and expansion. Each absorber consists of two end-capped frusta and a cylindrical shell. The intended… read more here.
