摘要
本文提出了利用正负透明片叠合实现图像相减的一种新方法,由于采用了阻零滤波处理,提高了输出相减像的对比度。文中介绍了工作原理并给出了实验例证,表明这是一种简便、有效、实用的方法。
This paper presents a new method of image subtraction with superimpose of positive-negative photographs. Using the operation of dc-stopping filter, the contrast of output subtracted image are improved. The principle is discussed and experimential results are given.
