摘要
图象旋转是图象处理中的一个基本操作,根据图象在邻近区域内连续的特点,该文提出一种基于高斯模板的图象旋转算法。实验结果表明,该算法能较好地消除图象旋转所产生的锯齿现象,图象多次旋转后失真较少,与最近插值和双线性插值相比具有较好的性能。
Image rotation is a basic operation in image processing.According to the feature that scenery is continuous in an image,an algorithm based on gauss template for image rotation is proposed.The experimental results show that it can eliminate the phenomena of zigzag caused in image rotation and reduce the image distortion after image rotates many times.It has a better performance than the algorithm of nearest interpose and double interpose.
