Abstract

This paper studied on shadow detection method on high resolution remote sensing image based on HIS space transformation and NDVI index. Firstly, the high resolution remote sensing image was transformed to HSI space, and the shadow of image could be detected with the characteristics of the low brightness and the high saturation in the area of shadow. Then according to the NDVI index of image, some of the ground objects, such as dark green grass, could be eliminated, and the shadow may be detected more efficaciously and accurately.
