ABSTRACT:
A system and methods for creating user definable windows for applying image processing, particularly useful in a post-production color correction equipment. The system allows a user of an image processing system such as a scene by scene color corrector to define a color region of interest in an image for purposes of applying image processing only to the region of interest, with automatic tracking of that region of interest over a plurality of frames in a scene. The user defined window, comprising a closed polygon, is converted on a frame-by-frame basis to a matte that is keyed with image processing such as color correction values. The user defined windows can be edited and stored and recalled for use in other frames. The color region of interest is automatically tracked from a beginning frame to the ending frame of a scene, with a vector window defined for each frame, so as to adapt to and compensate for changes in shape, size, and geometry of the region of interest during the succession of frames in the scene.
