OpenCV: Affine Transformations
WebJan 30, 2024 · Combining two warpAffine, shift and rotate image. I currently use the following sequence of code to first shift an image, then rotate the same image: M = np.float32 ( [ [1,0,20], [0,1,10]]) shifted = cv2.warpAffine (img,M, (y_size,x_size),flags=cv2.INTER_LANCZOS4) center_of_rot = (500, 500) M = … WebJan 8, 2013 · cv2.warpAffine takes a 2x3 transformation matrix while cv2.warpPerspective takes a 3x3 transformation matrix as input. Scaling. Scaling is just resizing of the image. OpenCV comes with a function cv2.resize() for this purpose. The size of the image can be specified manually, or you can specify the scaling factor.
