Cassini's radar images of Titan reveal far more details on the surface than are visible in optical camera photos. But they suffer from a lot of "noise," a salt-and-pepper appearance of random variation among pixel values. At the 2012 Lunar and Planetary Science Conference, Antoine Lucas and Oded Aharonson presented the results of their work "denoising" these data, producing beautiful, crisp images that reveal fine details of Titan's surface. On the left is an example radar image (a). Below (b) is a denoi
