Abstract

This paper investigates the suitability of graphical process unit (GPU) for a novel 3D object local descriptor named Signature of histogram of orientations (SHOT). SHOT presents a great balance between descriptiveness and robustness but its high complexity incurs heavy computational workload. We designed two parallel SHOTs on GPU to speed up the original serial counterpart. Experiment results show both the precise and approximate parallel algorithms exhibit outstanding speed performance. Moreover, we validated the descriptiveness of both parallel SHOTs were at high level through quantitative experimental comparisons.
