中文摘要: 针对图像受近红外光线参与的影响而出现偏色现象，介绍了一种基于RGB色彩空间的四带（RGB带和一个附加的近红外带）树木图像颜色校正方法. 该方法首先根据R-G差值图像，通过实验获取合适的阈值将四带树木图像二值化. 然后，利用中值滤波器和数学形态学对二值图像进行滤噪处理，提取出偏色较严重区域. 最后分区域进行颜色校正，达到消除近红外干扰的目的. 实验结果表明，该方法对部分常见含植物的场景图像有比较好的校正效果.

Abstract:A color correction algorithm for four-band (the RGB bands and an additional near-infrared spectrum) tree image based on RGB color space is proposed to correct the images which influenced by near-infrared spectrum. Firstly, based on the difference of R band and G band in the image, obtaining the best binarization threshold of four-band image through the experiment. Second, using the median filter and mathematical morphology to de-noise the binary images, and extracting the area which severely polluted by the near-infrared spectrum. At last, correcting images in different areas with different method, eliminating near-infrared pollutions in the image. The experimental results show that, the algorithm has good correction effect for the images which include plants.
