摘　　要：为了满足某在线监测系统对大数据量图像实时处理的需要,基于边界定位和对称性思想,提出了一种高速图像旋转算法.该算法较大程度地消除了基于Bresenham画线法的旋转算法易产生的图像边缘锯齿现象,并成倍地提高了图像的旋转速度.实验结果表明,该算法与当前典型的旋转算法相比在速度上具有较大的优势,并且保证了图像质量.In order to meet a certain online monitoring system＇s need of massive-data image＇s real-time processing, a high-speed image rotation algorithm based on boundary location and image symmetry is proposed. The algorithm can effectively solve the sawtooth problem that goes with the fast rotation algorithm based on Bresenham approach, and it also can accelerate the image rotation by times compared with the typical image rotation algorithms. The experimental results show that the proposed algorithm is superior to current typical algorithms in terms of rotation-speed and has better image quality.
