摘要

Enhancement of remotely sensed images is a challenging problem, since the enhanced image has to have animproved contrast and edge information while preserving the original radiance values as much as possible.In this paper, a scale aware enhancement method based on rolling guidance is proposed for remotely sensedimages. For each scale, a guidance image is defined and the approximation image is provided by an iterativejoint filtering of the approximation and guidance images. Then the extracted details are amplified through anadaptive scheme and added to the final level approximation layer to provide the resulting enhanced image. Acomparative study between the proposed methods with classical edge preserving filters and traditional methodshave been carried out by using several criteria. The proposed methods have an average of 12 improvementfor contrast gain (CG) metric and 81 improvement for enhancement measurement (EME) metric comparedto the closest comparison method.
