OpenCV - cv2.perspectiveTransform() not working for all the images

I used PerspectiveTransform to draw an outline around the detected image.

The cv2.perspectiveTransform() is able to draw a rectangle only for a few detected images but not for all the images.

Some of the detected images are not showing up with an outline.

What might be the reason of missing it?

Does it assume that the points may be outside the camera view and detected just the image without projecting an outline?

John

are all your images of type `float`? – Jeru Luke Jan 29 '17 at 12:17
@JeruLuke Yes all the images are 32 bit floats. – John Jan 29 '17 at 12:22
Maybe add some example images. – Adi Shavit Jan 29 '17 at 12:26
@AdiShavit Added example images. – John Jan 29 '17 at 12:35
Where are the rectangles in this image? An you show a success and a failure case? – Adi Shavit Jan 29 '17 at 12:36
