摘要 | It is crucial to enhance the lower contrast Remote remote sensing images to obtain more details information for further remote sensing image processing and application. In this letter here, a self-Adaptive remote sensing image contrast enhancement method has been proposed. The method is an improvement, based on gradient and intensity histogram equalization (GIHE) by using the advantage of histogram compaction transform (HCT). Firstly, we obtained two enhanced images by GIHE and HCT, respectively. Then furthermore, the two enhaceed images were normalized with a self-Adaptive paremeter, which based on standard deviation and mean of the gradient. Finally and then, we modified the normalized image by dual-gamma function for preserving the local details. It's evidenced that the proposed method have more richer details and better subjective visual quality, comparedwith the other methods. The experimental results depicted in terms of PSNR, MAE and Q. Comparing with the other methods, the proposed method had richer details and better subjective visual quality. © 2017 SPIE. |
