Detailed Description

This is a version of a representation presented in https://arxiv.org/abs/1412.6821 In that paper the authors are using the representation just to compute kernel. Over here, we extend the usability by far. Note that the version presented here is not exact, since we are discretizing the kernel. The only difference with respect to the original class is the method of creation. We have full (square) image, and for every point (p,q), we add a kernel at (p,q) and the negative kernel at (q,p)

Examples: persistence_heat_maps/create_pssk.cpp.

The documentation for this class was generated from the following file:
