INPAINTING

Let an image and a gap inside it where we know its position, is it possible to erase the gap?

In others words, is it possible from the surrounding information to stretch it inside the gap, and to restore the image as well as possible?. How to strech the surrounding information inside the gap?

We propose : "A Variational Model for Filling-In"(1.2 Mb, PDF)

Some results that we are getting:

Removing gaps on images: (click on the images to zoom)

Lenna Image with 17 holes	Reconstruction Result

Watching our program running:

• Inpainting the first hole(top-right) of Lenna by LevelSets(243 Kb, zipped Movie AVI)

Superimposed Text Removal. (Every character is considered as a gap)

Image with text to remove	Reconstruction Result

• Inpainting the Luminance channel of Farol by GrayScale(1.7 Mb, zipped AVI)
• Composed Movie "THE END"(0.8 Mb, GIF animated), (0.9 Mb, AVI)

More experimental tests ...

Up, a sequence of numbers from 0 to 9. Middle, the original image with a red hole on digit 6. Bottom, the result inpainting the gap smoothly extending the surrounding information into the hole in the isophote direrections (It's not the solution that we have in mind, but it's the logical solution from the boundary). To restore gaps from surrounding information is enough?. Or, do we need to incorparate knowlegde from Artificial Intelligence ?
