FlowInpainting

Reconstructs missing areas of an image with an inpainting algorithm.

Access to parameter description

The FlowInpainting algorithm performs inpainting operations in an image in order to reconstuct some missing or corrupted data, designated by a binary mask. It consists of locally extrapolating the searched data in the input image.
These techniques can be used, for example, for reducing strong ring artifacts in computed tomograpy images.
