WebJan 20, 2024 · Perform an affine warp using the cv2.warpAffine function, supplying our input image and computed rotation matrix, M The result is an image that has been rotated degrees. The problem with using OpenCV’s functions to rotate an image is that they require two lines of code — one to construct the rotation matrix and then another to perform the ... WebRotation and translation of images are among the most basic operations in image editing. Both fall under the broader class of Affine transformations. Before studying more complex transformations, you should therefore first learn to rotate and translate an image, using the functions available in OpenCV.

WebThe Affine Transformation is a general rotation, shear, scale, and translation distortion operator. That is it will modify an image to perform all four of the given distortions all at the same time. These are all 'linear' distortions, by which I mean two straight parallel lines present in an image will remain straight and parallel.
