摘要
本文提出了一种采用普通照相并结合滤波技术实现图象相减的方法.文中对相减原理作了详细分析,给出了实验例证,最后讨论了几个与相减输出有关的重要因素.
in this paper,a method of image subtraction using photograph and filter technique is introduced.The principle of image subtraction is analyzed in detail and experimental results are given.Finally,some important factors, which have an effect on output subtraction image,are discussed.
