Rotate images (correctly) with OpenCV and Python

WebThe open CV rotate () method is utilised to rotate a two-dimensional image at various angles congruent with 90-degree angles. When we write a code that utilizes the [cv::rotate] function, it helps in rotating an array in three different orientations, which the user has entered. Syntax of Open CV rotate (): WebHowever, with position, scale, and orientation, you would have to use a 5-D Hough transform (2 DOF for position, 1 for scale, 1 for orientation), which might be computationally quite demanding. As an alternative, you might want to look at SIFT or one of its extensions like SURF. It sounds like they can be adapted to do the job.
