红外测量图像自适应彩虹码伪彩色编码方法

摘要

由于空中目标测量图像灰度往往不均衡,采用传统彩虹码进行伪彩色变换时往往造成色彩分布极不均匀,整幅图像仅仅显示一、二种颜色.基于此问题,本文根据测量图像灰度分布特性,利用自适应阈值理论,对传统彩虹编码进行改造,提出了一种基于测量图像的自适应伪彩色编码方法.实验结果表明:变换后得到的伪彩色色彩丰富,完整地覆盖了全部有效灰度范围,且算法具有较好的自适应性.%Aiming at the gray intensity of objective measurement image is not always balanced, and it often leads to uneven color distribution by pseudo-color coding base on rainbow-code, and the whole image shows only one or two color, based on this problem, we measure the image intensity distribution in accordance with adaptive threshold model code to transform the traditional rainbow, an adapative pseudo-color image coding method based on measurement image is proposed.Experimental the results show that: the pseudo-color transformation is colorful and it can cover the effective intensity range completely adaptabilit of the algorithm is excellent.
