Examplar-based video inpainting with motion-compensated neighbor embedding
This paper describes a video inpainting algorithm based on motion-compensated neighbor embedding. The unknown pixels are estimated as a linear combination of the K closest patches using motion-compensated neighbor embedding. The algorithm is first assessed by assuming the motion information of the masked pixels to be known. This assumption is not realistic in video editing (object removal) applications. It however helps isolating the various problems for the sake of analysis. Different approaches are then assessed in the context where the motion information of missing pixels is unknown. Experiments on several videos show the benefits of the proposed approach which lead to natural looking videos with less annoying artefacts than when using a template matching technique.
