The effect of spatial information characterization on 3D local feature descriptors: A quantitative evaluation
作者：
Highlights：
• The effect of spatial information encoding (SIE) on 3D local descriptors is emphasized.
• Eighteen types of 3D local descriptors with different SIE approaches are proposed.
• Quantitative evaluation of SIE approaches is performed on three standard datasets.
• The merits, demerits and suitable applications of different SIE ways are summarized.
• Instructive guidance is concluded for the design of a 3D local descriptor.
