Detailed Description

template<typename T>
struct SpectralDecompositionDataPointsFilter< T >

Spectral Decomposition Filter (SpDF) is a sampling algorithm based on spectral decomposition analysis to derive local density measures for each geometric primitive. First, we identify the geometric primitives along with their saliencies using the tensor voting framework. Then, we derive density measures from saliencies: if the density for each geometric primitive is less than the desired density, we stop; else we sub-sample each over-represented geometric primitive, and re-iterate. As output, we have a uniform sampled point cloud enhanced with geometric information.
