WebApr 12, 2024 · However, higher computational complexity makes PFH unsuitable for real-time applications. Therefore, Fast Point Feature Histogram (FPFH) (Rusu et al. 2009, 2009) is proposed to solve this problem. It consists of two steps. The first step is the construction of the Simplified Point Feature Histogram (SPFH).
