inpainting (filling in missing parts of image)

Does anyone know how to fill in missing parts of an image? Ex: A portion of a photo is removed, and Matlab fills it in based on the surrounding points.

Answer 1

[Image Analyst]

There is a function called roifill() in the Image Processing Toolbox that can do inpainting.

Answer 2

[Walter Roberson]

John D'Errico's MATLAB File Exchange Contribution inpaint_nans might be of benefit.

[John D'Errico]

As Walter points out, inpaint_nans is the standard answer. However, depending on what was removed, any such tool can only fill in smoothly from the boundaries. Texture inpainting, or intelligent inpainting, wherein a missing eye is replaced, these are far beyond any such unintelligent tool.
