摘要
通过分析研究抑制蓝色分量和亮度线性补偿这2种阴影补偿算法,利用阴影区域与其同质区信息相似的特点,把这2种算法进行合并与改进,提出基于RGB和HSI色彩空间的阴影补偿算法。实验数据表明,该算法对遥感影像上阴影区域进行补偿时,在不改变非阴影区域信息的情况下,提高算法适用性。
This paper analyzed the suppressing B component method and Linear-correlation method at first. After improving and merging these two methods, this paper presented a shadow compensation method based on RGB and HSI color space. Experimental results indicate that this proposed method can improve the visibility of features in shadowed areas and retain the value of non-shadowed regions. The results show that the properties and applicability of the proposed approach is good.
