An action matte image is produced from a input sequence of images by producing a current clean plate image representing the background from the input sequence of images; comparing the current clean plate image and a current input image of the input sequence of images; and constructing the action matte image representing the foreground image in response to the result of the comparison, thus allowing the extraction of action sequences or the separation of the images of actors from an image comprising image data relating to both the actors and the general background without the requirement for a blue background. Another aspect provides a method and system for automatically identifying and defining regions of an image which correspond to a moving image. |
