On luminance reduction in high dynamic range synthetic aperture radar images

High dynamic range images enable more detailed information regarding the content. By performing luminance compression, images can be prepared for the traditional low dynamic range reproduction. There are numerous ways to perform the compression (tone-mapping), but the content may affect the image quality. The reduction of dynamic range may produce unwanted effects (e.g. due to noise) and can be tailored for specific image content. In this paper we analyze several examples related to synthetic aperture radar (SAR) as images with high dynamic range.
