| 摘 要： | 航空影像中存在的不均匀光照现象是遥感影像处理中要解决的一个重要问题。现有的MASK匀光处理技术能够在一定程度上解决这类问题。但是经过MASK匀光处理后的图像存在反差不均匀现象,即原始图像中较暗区域经过匀光后明显地表现出反差较低,而亮的区域则反差较大。针对此不足,提出了一种基于反差一致性改进的MASK匀光算法。实验证明,该方法能够迅速提高暗区域反差,抑制亮区域反差,达到整体影像的反差一致性,获得更好的匀光效果。

| Abstract: | The uneven illumination of aerial image is an important problem in image processing.The existent MASK dodging method can solve this kind of problem in some degree.However the contrast is inconsistent in the image after MASK dodging processing,namely,the contrast in dark area of original image is low obviously, and that in light area is high.So,according to this,an improved MASK dodging method based on contrast consistency processing was proposed in this paper.The experiment showed that the proposed method c... |
