837e41f9a7 Add -ws flag for cornerSubPix params (backported from 4.x).
Add flags to set the camera intrinsic parameters as an initial guess (can allow converging to the correct camera intrinsic parameters).
Add -imshow-scale flag to resize the image when displaying the results.
Add -enable-k3 flag to enable or disable the estimation of the K3 distortion coefficient.

Update text_detection.py
there is a recent change, how `std::vector<int>` is wrapped in python, 
it used to be a 2d array (requirig that weird `[0]` indexing), now it is only 1d

90be83ae99 Fix an arg for calcHist() in demos
`float* histRange = { range };` doesn't make much sense. `histRange` is
an array of array(s), so it should have a type of ptr to ptr. Strangely
some domos are correct as well as the example for the function
