Moving object removal and background completion in a video sequence

Abstract

A computer vision technique is introduced to remove a moving foreground object in a video sequence for digital post-processing. Recently various digital special effects are employed in generating video production. This paper introduces one of the digital special effect techniques, moving object removal and background completion. To find a moving foreground object in a video sequence, we track background features frame by frame to register background motion. After registration, we extract and remove the moving object in every frame. The empty region of the object in a frame is completed by background images transformed from other video frames. Several experiments show that the proposed technique can be used to employ special effects in digital video post-processing.
