Abstract
In order to restore the visual characteristics of shadow-obscured terrain objects in high-resolution images and enhance the accuracy of terrain object extraction,land-use classification,and water resource investigation,we proposed a hybrid radiative transfer and geometric optics model for the recovery of visual features of shaded objects(RTGO-MRVFSO),which could improve the brightness characteristics of obscured objects by enhancing the scattering intensity in the shadowed areas of images.The overall accuracy of land-use classification has been improved by 67.88%,IOU has been improved by 66.00%,and the F1-score has been improved by 56.66%.The result shows that RTGO-MRVFSO can adaptively enhance the visual characteristics of shadow-obscured terrain objects and further improve the extraction accuracy of high-resolution image terrain objects.关键词
