Fast/Robust Template Matching

TEMPLATE_MATCHING is a CPU efficient function which calculates matching score images between template and (color) 2D image or 3D image volume.

It calculates:
- The sum of squared difference (SSD Block Matching), robust template matching.
- The normalized cross correlation (NCC), independent of illumination, only dependent on texture

The user can combine the two images, to get template matching which works robust with his application.

Both matching methods are implemented using FFT based correlation.

Try the examples.
