This invention concerns the tracking of objects in video data for artificial vision; for instance for a bionic eye. More particularly, the invention concerns a vision enhancement apparatus for a vision-impaired user. In other aspects, the invention concerns a method for enhancing vision and software to perform the method. The image processor operates to process video data representing images of a scene. Automatically detect and track a user selected object, such as a face, in the images. And, automatically modify the video data, by reserving a user selected area of the displayed images for displaying the tracked object as a separate video tile within the scene. The separate video tile remains in the selected area despite movement of the camera relative to the scene, or movement of the user relative to the object or the scene.

The disclosed Off-Road Vehicle Vision Enhancement System is for all terrain vehicles operating in extreme off road environments. When an all terrain vehicle is operating in areas where there are large obstacles to traverse the operator needs to be able to maneuver the vehicle over the obstacles with the utmost of care and precision. The operator needs to be able to see the precise placement of the wheels over the obstacles to achieve optimum ground clearance and avoid getting hung-up. The Off-Road Vision Enhancement System includes a retractable protective housing located under the vehicle containing cameras which communicate to the operator the precise relationship of his wheels traversing the obstacles. The retractable housing is designed for simple operation, maximum protection of the cameras and self cleaning of accumulated debris.
