| 摘 要： | 以白光密度伪彩色编码物理实验为基础,通过数学模型分析,推出各级图像的强度与原始灰度之间的最佳算子为弦函数,以相位调制数字图像实现了伪彩色增强.基于RGB真彩色显示系统原理和24位真彩色图像数据存储特点,提出了相位调制数字图像伪彩色处理方案,并与现行伪彩色处理软件做比较,得出使用弦函数算子进行相位型伪彩色处理优于其他伪彩色算法的结论.所提方案能处理多种常见格式的灰度图像,使任意位深的灰度图像都能转换为24位真彩色.

| Abstract: | Pseudo-color enhancement comes true with phase-modulated digital image.By some mathematic models in the pseudo-color coding experiment with white light density,cosine or sine function will be concluded as the best arithmetic operator between the image the intensity of all levels and original grey values.The pseudo-color coding scheme based on RGB true color displaying theory and data stored features of 24 bits image have been proposed.After the comparison with some prevailing software on pseudo-color processing,the pseudo-color processing based on cosine or sine operator with phase is better than other pseudo-color algorithms.Some grey images with ordinary formats can be processed by the scheme,and many grey images can be transformed to true color images with 24 bits. |
