What is Image Transformation?
Image transformation performs two role:
- Image translation : image translation simply shifts the position of an image.
- Image rotation : image rotation makes the image rotate by $\theta$.
Image translation
To do the image translation, we can use
cv2.warpAffine(image, T, (width, height)) where
Image rotation
To do the image rotation, we can use
cv2.getRotationMatrix2D(rotation_center_x, rotation_centery, angle of rotation, scale) where
