3D Point Cloud Simplification Based on k-Nearest Neighbor and Clustering

Figure 8

Simplification results of the Fandisk model (triangulated); the original number of points is 103,570. (a) Simplified using the novel method with parameters of cluster size and deleted cluster number (2590, 310) and (9759). (b) Simplified using Shi et al. method [16] with parameters of space interval and normal vector deviation threshold as (0.076, 0.13) and (9682). (c) Simplified using the 3D Grid method [39] with parameters of space interval and standard normal vector deviation as (0.0696, 0.41) and (9694).
