A Fast-High-Quality Image Rotation Approach Based on Bresenham Algorithm

Incrementa-l positioning property of Bresenham algorithm was introduced into image rotation. An approach based on Bresenham algorithm is proposed to accelerate the rotation of image.The proposed approach decreases the number of float-point and float-integer conversion operations,and is much more efficient than the current image rotation methods,but with high quality. Experiments show that the proposed approach is four times more efficient than the existing methods,and it facilitates hardware implementation as well.
