Object tracking for artificial vision
First Claim
1. A vision enhancement apparatus for a vision-impaired user, comprising:
- a high resolution video camera on the vision-impaired user for filming a scene in front of the vision-impaired user;
a video display viewable by the vision-impaired user; and
an image processor for processing high resolution video data from the video camera and displaying the resulting images on the video display, the processor automatically detecting one or more objects and human heads in the displayed images of the scene, the processor processing the images to identify human heads and causing an alert to the user of newly identified human heads the processor receiving a signal indicative of the vision-impaired user selecting an object or a head from the one or more objects or human heads in the displayed images, the processor automatically detecting and tracking the user selected human head, and automatically modifying the video data, by displaying the selected head as a separate video tile within the scene, the separate video tile located in a part of the displayed images that is more visible to the vision-impaired user.

Abstract
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.

19. A method for enhancing vision for a vision impaired user, comprising the steps of:
-
processing high resolution video data representing images of a scene in front of the vision-impaired user; displaying the resulting images to the user; automatically detecting one or more objects or human heads in the displayed images; identifying the objects or human heads; alerting the user of newly identified objects or human heads; the user selecting an object or human head in the displayed images; automatically detecting and tracking the user selected human head; and automatically modifying the video data, by displaying the tracked human head as a separate video tile within the scene, the separate video tile within the scene located in a part of the displayed images that is more visible to the vision-impaired user. - View Dependent Claims (20)
