Remote sensing image enhancement via bilateral filtering

Abstract

Remote sensing image enhancement methods have to increase the contrast and emphasize the edges, while preserving the color. In this study, an enhancement method based on bilateral filtering is proposed. We propose to extract the details of the image by a multiscale bilateral filter and add these details to the original image using a weighting scheme. Visual results and evaluation metrics show that the proposed method, enhance the image better than the former methods while it better preserves the original color information.
