Detailed Description

template<typename TOutputImage>
class rtk::LaplacianImageFilter< TOutputImage >

Computes the laplacian of the input image.

Computes the gradient of the input image, then the divergence of this gradient. The exact definition of the gradient and divergence filters can be found in Chambolle, Antonin. "An Algorithm for Total Variation Minimization and Applications." J. Math. Imaging Vis. 20, no. 1-2 (January 2004): 89-97. The border conditions are described there.
