Abstract
Image data representing a moving image by a sequence of image frames each containing an array of pixels. A distinctive characteristic of an image frame is identified and image data is modified in response to process iterations. For each iteration, a tracking parameter is generated (1504) and the rendering of said object is controlled (1506) in response to the tracking parameter. An output image is displayed in response to the application of the controlled object so that tracking and display operations are performed on a frame-by-frame basis to facilitate creative manipulation of control parameters and tracking locations.
