摘要
本文提出了一种图象微分法。这种微分法是利用假彩色编码,将同时得到的一张图片的离焦象和准焦象实时迭加,从而得到该图片的假彩色微分象。此法简单易行,使用方便,可实时地获得假彩色轮廓突出的图象。文中还给出了实验结果。
In this paper,a new technique of image differentiation is discribed.Inthe technique differentiation image is displayed as the result of addition of one pri-mary coloring focusing image and another primary coloring defocusing image.Wehave shown that this technique is simple,versatile and economical for real-time enhancement of edge of image.
