Description
InputArray concept as i understand can work with std::vector<Mat> or only one Mat, but in mixChannels the second variant leads to incorrect work
core/source/convert.cpp line 511
int i, nsrc = (int)src.total(), ndst = (int)dst.total();
Using function total with no arguments to aquire the total number of matricies in InputArray is incorrect in case of Mat inserted in the proxy class.
I think in that case using std::vector or only one Mat should leads to the same behaviour.
So it is the problem inside InputArray.size() function. Matrix.cpp line 1019-1023
