摘要

A level of detail-transformation adaptive enhancement method for image contrast includes: dividing a remote sensing image into a plurality images of different levels of detail, the lowest level of detail defined as L and the highest level of detail defined as H, and gradually transforming an image Image_iof an arbitrary level of detail i between the image Image_Hof the highest level of detail H and the image Image_Lof the lowest level of detail L from Image_Lto Image_Hthrough the following equation: Image_i=R_i×Image_H+(1−R_i)×Image_L. The image Image_Hof the highest level of detail H is an image Image_ACEproduced with adaptive contrast enhancement processing, or an image produced with a contrast enhancement method such as Gaussian or histogram equalization; the image Image_Lof the lowest level of detail L is an image Image_LCEproduced by common linear contrast enhancement.
