In image processing it is sometimes necessary to rotate the image transformation, but the image several times in the small angle rotation transformation, it will produce distortion. Improved algorithm is in the process of rotating the image back to the original image is rotated first position, then rotate to the desired location. The algorithm for image using multiple rotation transformation experiments, experimental results show that with the way in stepping rotation algorithm, while improving the algorithm to better maintain the rotation of the details of the image, reducing image distortion.
