Dear @yishiliuhuasheng ,
I did not understand why you use the inverse H to create the warped_image instead of the H you just calculates. Could you explain to me?
This is the code that intrigues me:
H = cv2.getPerspectiveTransform(np.float32(four_points), np.float32(perturbed_four_points)) H_inverse = inv(H) inv_warped_image = cv2.warpPerspective(gray_image, H_inverse, (320, 240)) warped_image = cv2.warpPerspective(gray_image, H, (320, 240)) # grab image patches original_patch = gray_image[y:y + patch_size, x:x + patch_size] warped_patch = inv_warped_image[y:y + patch_size, x:x + patch_size]
Thank you
