Abstract

Chandrayaan-1, India´s first mission to moon was launched on 22^nd Oct 2008. It carried a Moon Impact Probe which impacted the moon´s surface on 14 Nov 2008. MIP had an imaging camera called Moon Imaging System (MIS) to take the pictures of moon´s surface while descending. All the images taken during flight were observed to have a certain kind of periodic impulse noise. The present paper describes the approaches used to restore MIS images which include characterization of noise. Restoration of images is attempted in spatial as well as in frequency domain. Frequency domain restoration turned out to be better in terms of noise cleaning while retaining sharpness of the images.
