| 摘 要： | 针对大旋转角情况下三步旋转算法的复杂性和灰度误差随着旋转角度的增加而迅速增加问题，提出了一种修正的三步平移旋转算法，它在大旋转角度时仍具有较小的复杂性和较高的图像质量．实验结果表明了该算法的正确性和有效性．

| Abstract: | The computational complexity of three pass algorithms and its residual error
increases with the size of rotation angles under large angles. An improved three pass translation
rotation algorithm is developed and tested which has the less computational complexity under a
large rotation angle while preserving high quality rotation. The theoretical analysis and
experimental results have demonstrated the feasibility and validity of this algorithm. |
