Texture-Aware Deblurring for Remote Sensing Images Using l(0)-Based Deblurring and l(2)-Based Fusion

Abstract

This article presents an image deblurring method using l(0)-norm-based deblurring and l(2)-norm-based texture-aware image fusion for remote sensing images. To restore the details of blurred texture, the proposed method first performs texture restoration by fusing the restored results using Richardson-Lucy deconvolution and unsharp masking. Next, we analyzed the intensity and dark channel properties of remote sensing images and perform the l(0)-norm-based deblurring using the intensity and dark channel priors. Although the l(0)-norm-based deblurring can provide a significantly restored result, it cannot overcome the loss of the texture region. On the other hand, the proposed l(2)-norm-based image fusion method can preserve both sharp edges and texture details. In the experiments, we demonstrate that the proposed method can provide better restored results than existing state-of-the-art deblurring methodswithout oversmoothing and undesired artifact.
