`ABSTRACT
`(57)
`_
`_
`_
`Motion picture scenes to be coloriZed/depth enhanced (2D
`>3D) are broken into separate elements, backgrounds/ sets or
`motion/onscreen-action. Background and motion elements
`are combined into composite frame Which becomes a Visual
`reference database that includes data for all frame offsets used
`later for the computer controlled application of masks Within
`a sequence of frames. Masks are applied to subsequent frames
`of motion objects based on Various differentiating image pro
`cessing methods, including automated mask ?tting/reshap
`ing. Colors and/ or depths are automatically applied to masks
`throughout a scene from the composite background and to
`motion objects. Areas never exposed by motion or foreground
`objects in a series of images may be partially or fully realis
`tically draWn or rendered and applied to the occluded areas of
`the background and then automatically applied throughout
`the images to generate of minimal artifact or artifact-free
`secondary Viewpoints When translating foreground objects
`horizontally during 2D_>3D COHVerSjOIL
