Abstract
An apparatus and method for generating a conformal window in a video tracking system. Each of the lines within the conformal window comprises a sub-window which is resized for each frame of video signal. The composite window comprising all the sub-windows is also resized vertically for each frame. The target image sub-windows are divided into left and right edge regions and a central region and are processed based on the density of pixels in the sub-window for each new frame. The target image is apportioned vertically into top and bottom regions and a central region, and lines of target image detail are processed to delineate new top, bottom and central regions for each subsequent frame of video signal. The resized window gradually assumes an orientation which conforms to the target image orientation.
