| 摘 要： | 针对异源遥感影像由于辐射水平差异导致地物在相邻图像上亮度值存在差异的现象,分析了造成影像间色调差异的各种原因以及现有处理方法在进行影像间色彩平衡处理时存在的问题,实现了基于Wallis滤波器进行匀光的相关算法,并通过多组匀光实验取得了较好的色彩平衡效果。

| Abstract: | As to luminance differences due to different radiation between multi - source remote sensing images, all factors causing the color difference and the shortcomings of present methods are analyzed, and then a dodging arithmetic calculation method based on Wallis filter is realized, which balances the color tone and achieves the good effect through dodging experiments. |
