Inpainting

Inpainting

Inpainting is the process of reconstructing lost or deteriorated parts of images and videos. For instance, in the case of a valuable painting, this task would be carried out by a skilled image restoration artist. In the digital world, inpainting (also known as "image interpolation" or "video interpolation") refers to the application of sophisticated algorithms to recover lost or corrupted parts of the image data.

Applications

There are many objectives and applications of this technique.Restoring an image to remove noise, improve brightness, color and details.

In photography and cinema, is used for film restoration; to reverse the deterioration (e.g., cracks in photographs or scratches and dust spots in film; see infrared cleaning). It is also used for removing red-eye, the stamped date from photographs and removing objects to creative effect.

This technique can be used to recover the lost blocks in the coding and transmission of images, for example, in a streaming video. It can also be used to remove logos in videos.

Methods

A common method is use differential equations with boundary conditions for continuity (a seamless fit). [cite journal
