List of all members.

Detailed Description

Laplacian of Gaussian image.

Todo:

Check the correctness of the constructor from a float image. It converts a float image to a greylevel image.
function qgar::LaplacianOfGaussianImage::PRIVATEbuildLOGImage returns a float image, which is then duplicated in constructors!
