Abstract: This paper puts forward a novel approach for restoration of low-rank information from RS images based on matrix completion, and carried out some denoising and inpainting experiments using the singular value thresholding operator through determinate sampling and warm starting. The results indicate that the effect of our method is dominant when addressing the recovery of missing information caused by polluting and sheltering, and moreover, the approach can preserve details and textures in the images and make structures coherent while restoring original images, which shows great potential in the application of RS-image denoising and thick clouds removal. Especially when images possess low-rank characteristics such as similar structures and regular textures, the performance of the approach proposed will be better.

Key words: remote sensing image restoration, low-rank information recovery, matrix completion, singular value thresholding, thick clouds removal
