Aiming at the striping noise existing in IIM (the Imaging Interferometer carried by Chang’E Lunar Orbiter) data,the Fourier transform algorithm and the linear interpolation algorithm are experimentally utilized for strip noise removal in IIM images.A modified linear interpolation algorithm is proposed,which combines low rank algorithm with high rank algorithm.After noise location,high rank interpolation or linear interpolation is used by judging whether the pixel difference between the upper and lower lines goes up to the threshold.Comparison of mean values,standard deviations,and the IQ (Image Quality) factor shows that this modified method is evidently superior to the linear algorithm because the IQ factor of two methods is respectively 13.908 and 19.842 8.
