A method is used to remove high building shadows in true color and color infrared urban aerial images based on the theory of color constancy.The spectrum ratio and Otsu threshold segmentation methods are used to detect building shadows in true color and color infrared urban aerial images.Then, based on the shadow detection result,one of the color constancy algorithms shades of gray(SoG) is used to remove the shadows in aerial images with different p values of Minkowski norm.Finally, the shadow removal resul...
