| 摘 要： | 本文提出了一种彩色图像相减的新方法.该方法利用互相错动半个周期的两组三色光栅,在黑白底片上分别对待处理的两幅图像进行一次编码记录,然后在白光处理器上对黑白编码片进行彩色译码,即可实现彩色图像的强度相减,文中讨论了三色光栅实时生成和两组三色光栅条纹自动错动半个周期的方法,并给出了实验结果。

| Abstract: | A new method for color image subtraction is proposed in this paper. The two color images encoded separately by two three-primary color gratings with an effective halfperiod shift of color fringes in one step are recorded on the same black-white film. The three-color gratings are formed in real-time by in torference of symmetric orders of 2-D grating diffraction and three-color filters, and the half-period change of color fringes is realized by simple polarization spatial filters. The intensity subtraction of two color images then can be obtained easily by decoding in a white-light processor. An experimental example is given. |
