Dear editor, Video inpainting is a new technology of recovering the lost motion vectors or image blocks during the video sequence transmission. It aims to speculate the correct value of missing voxels from a given video to achieve the automatic inpainting and make the inpainted video frames present a natural visual effect. However, video inpainting remains challenging owing to the difficulties coming from computational complexity, complex scenarios and the high requirement on spatial and temporal consistency.
