WebAffine transformations are nice, but they impose certain restrictions. A projective transformation, on the other hand, gives us more freedom. It is also referred to as homography. In order to understand projective transformations, we need to understand how projective geometry works. WebAffine Transformation¶ In affine transformation, all parallel lines in the original image will still be parallel in the output image. To find the transformation matrix, we need three points from input image and their corresponding locations in output image. Then cv2.getAffineTransform will create a 2x3 matrix which is to be passed to cv2 ...
