Description

Problem: init_module() function(s) can be called before the constructors of AlgorithmInfo's used inside init_module().
See my commit r7856 where I've already fixed this problem for some classes.

Right now there are several new algorithms which uses unsafe initialization pattern. At least the following from features2d module:
  • gftt_info
  • harris_info
  • dense_info

I think OpenCV should use a macro to hide typical part of algorithm setup and avoid this initialisation problem for future Algorithms.
