Query: Image Processing using Smooth Ordering of its Patches   We propose an image processing scheme based on reordering of its patches. For
a given corrupted image, we extract all patches with overlaps, refer to these
as coordinates in high-dimensional space, and order them such that they are
chained in the "shortest possible path", essentially solving the traveling
salesman problem. The obtained ordering applied to the corrupted image, implies
a permutation of the image pixels to what should be a regular signal. This
enables us to obtain good recovery of the clean image by applying relatively
simple 1D smoothing operations (such as filtering or interpolation) to the
reordered set of pixels. We explore the use of the proposed approach to image
denoising and inpainting, and show promising results in both cases.
