【摘要】 本文提出用白光按两张图片之间的差别假彩色编码的一种方法.证明了用不同颜色的两个光源足以检验人眼所能同时区分的两张连续灰度图片之间的差别,并用电视模拟系统对假彩色编码输出像进行了选色和微分处理,增强了所需要的差别信号.理论分析与实验相符.最后,讨论了这种方法可能的实际应用.更多还原

【Abstract】 In this paper, a optical pseudocolor encoding method upon the difference between two photographs is presented. We show that the difference between two pictures with continuous change in gray which is discriminated simultaneously by eyes, can be detected by use of two sources of different color. The pseudocolor image from the optical system is processed in select-color and differentiation by video system, thus the signal of difference is enhancad. The theory is agreement with experiment. Finally, some applications are discussed.更多还原
