数字分色技术在公安图像处理中的应用

The Application of the Digital Monochrome Technology in Public Security Image Processing Technology

传统分色照相是利用色光及滤色镜,改变被摄客体在某一选定色光波段的反射光亮度分布,以加强或减弱被摄客体颜色之间差别的一种专门摄影技术。使用数字图象处理软件中的数字分色技术,同样可以有效处理不同颜色之间的亮度反差,与传统方法相比,可选色光波段多,操作方便,分色效果好于传统分色照相技术,在一定程度上可以取代传统分色技术。

Traditional Color-Separation Photography makes use of the polychromatic light and color filter to change the reflective light distribution of the object taken picture in certain color light wave bond. As a photography technology, it also strengthens or weakens the color of the object taken picture. Using digital monochrome technology of digital image processing software could deal with the light contrast of different colors effectively. Compared with the traditional way, the amount of optional light wave bond is more, it is much convenient, color-separation effect is much better than the old, and on some degree it could instead the old.
