Detailed Description

template<typename PointInT, typename PointNT, typename PointOutT>
class pcl::IntensityGradientEstimation< PointInT, PointNT, PointOutT >

IntensityGradientEstimation estimates the intensity gradient for a point cloud that contains position and intensity values.

The intensity gradient at a given point will be a vector orthogonal to the surface normal and pointing in the direction of the greatest increase in local intensity; the vector's magnitude indicates the rate of intensity change.
