Conceptual representation of nonrigid point correspondence methods for the registration of textured LRS data. The three points of interest in this figure are highlighted with numbers. 1: Real world objects with continuous surface descriptions are discretized into the LRS datasets with information loss related to the resolution of the LRS system (represeted with the light gray arrow). 2: Incorporation of intensity information via texture mapping resulting in textured LRS dataset, this step incurs information loss related to the limited resolution of the spatial coordinates with respect to the texture image. 3: two methods to register textured LRS datasets, (a) nonrigid 2-D image registration and (b) nonrigid 3-D point matching.
