Handling error in bad input and affine_transform of contours

[ujjaldas1997]

1. The program call.py shows an error for an input containing no QR, which need to be handled.
2. When an input image contains a rotated image(rotated by some angle), the output of the image shows the identified contours of the input image format, whereas the output image is transformed according to right, top and bottom of contours. For example --
   Input -
   
   and Output -

Is this issue still open?

@Griffintaur @ujjaldas1997 I think this should be split to 2 different issues.
The first one is actually not an easy fix, I tested with one image without QR code, but the program by mistake, identified a weird part of image as QR code.
And patterns are less than equal to three was printed instead of any error.
I believe other scenario could happen if tested with more images without QR code, so it deserves a separate issue.

Ok then. Go ahead
