Detailed Description

template<typename PointInT, typename PointOutT>
class pcl::BilateralUpsampling< PointInT, PointOutT >

Bilateral filtering implementation, based on the following paper: * Kopf, Johannes and Cohen, Michael F.

and Lischinski, Dani and Uyttendaele, Matt - Joint Bilateral Upsampling, * ACM Transations in Graphics, July 2007

Takes in a colored organized point cloud (i.e. PointXYZRGB or PointXYZRGBA), that might contain nan values for the depth information, and it will returned an upsampled version of this cloud, based on the formula:

\[ \tilde{S}_p = \frac{1}{k_p} \sum_{q_d \in \Omega} {S_{q_d} f(||p_d - q_d|| g(||\tilde{I}_p-\tilde{I}_q||}) \]

where S is the depth image, I is the RGB image and f and g are Gaussian functions centered at 0 and with standard deviations $\sigma_{color}$ and $\sigma_{depth}$
