摘要
本文为克服频域相关技术对图像旋转的敏感性,提出了一种有效的旋转校正方法,它经空域加权,频域滤波,角度筛选等一系列处理,能很正确地求出旋转角.本文还将该法与空域法有机地结合在一起,从而生成了一种在匹配效果、匹配速度和算法适应性上都比较理想的新的匹配算法.
A spatial domain and frequence domain two stage image match method is developed. Taking both the. advantages of spatial domain techniques and frequence domain one which is improved provide an insensative to grey level and noise, rotation invariance, yet fast image match method.
