Digital Image Inpainting

[Tristan06006]

Inpainting is an artistic synonym for image interpolation, and has been circulated among museum restoration artists for a long time. The notion of digital inpainting was firstintroduced in the paper by Bertalmio-Sapiro-Caselles-Ballester (SIGGRAPH 2000). Smart digital inpainting models, techniques, and algorithms have broad applications in image interpolation, photo restoration, zooming and super-resolution, primal-sketch based perceptual image compression and coding, and the error concealment of (wireless) image transmission, etc.

Can you please explain a little what is image interpolation?

[Tristan06006]

In one word, Its a process to make a larger image from small image.

Interpolation is the process by which a small image is made larger.  Software tools stretch the size of the image and generate pixels to fill in the blanks.  Interpolated images produce smoother lines and a better large print than if the original, small image was simply printed large. Image interpolation tools enable low mega pixel count digital camera owners (or small format film camera owners) to print BIG pictures with excellent results.
