Abstract

From the shadow processing of high-resolution aerial remote sensing images, this paper analyzed the features of shadow in color space. Using combined thresholds of 3 channels in HIS color space and Gaussian function, the authors detected shadow area and its multi-scale geometric details which can compensate shadow area. The experiments prove that this method can maximize the retention of the original features in shadow area and get more reasonable compensation results, thus ensuring accuracy and reliability of the follow-up imaging.
