We introduce a new representation for video which facilitates a number of common editing tasks. The representation has some of the power of a full reconstruction of 3D surface models from video, but is designed to be easy to recover from a priori unseen and uncalibrated footage. By modelling the image-formation process as a 2D-to-2D transformation from an object’s texture map to the image, modulated by an object-space occlusion mask, we can recover a representation which we term the “unwrap mosaic”. Many editing operations can be performed on the unwrap mosaic, and then re-composited into the original sequence, for example resizing objects, repainting textures, copying/cutting/pasting objects, and attaching effects layers to deforming objects.

Damit kommt man der SciFi-Vision, dass man z.B. in einem vorhanden Spielfilm den Hauptcharacter mit seinen eigenem Gesicht bestücken könnte doch wieder einen beachtlichen Schritt näher.
