Query: Hierarchical Approach for Total Variation Digital Image Inpainting   The art of recovering an image from damage in an undetectable form is known
as inpainting. The manual work of inpainting is most often a very time
consuming process. Due to digitalization of this technique, it is automatic and
faster. In this paper, after the user selects the regions to be reconstructed,
the algorithm automatically reconstruct the lost regions with the help of the
information surrounding them. The existing methods perform very well when the
region to be reconstructed is very small, but fails in proper reconstruction as
the area increases. This paper describes a Hierarchical method by which the
area to be inpainted is reduced in multiple levels and Total Variation(TV)
method is used to inpaint in each level. This algorithm gives better
performance when compared with other existing algorithms such as nearest
neighbor interpolation, Inpainting through Blurring and Sobolev Inpainting.
