在图像处理中，有时需要对图像进行旋转变换，但是图像在小角度多次旋转变

换后，会产生失真．改进的算法是在图像旋转过程中先将图像旋转回原始的位置，再旋

转到目标位置．利用该算法对图像进行多次旋转变换实验，实验结果表明，与以步进方

式的旋转算法相比，改进算法在旋转的同时较好地保持了图像的细节信息，减小图像的

失真．-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.
