Video applications for mobile communications have been designed mostly for content creation, access, and replay...By the same token, few truly innovative and usable video or image analysis applications are available for mobile phones....

[We] designed four novel solutions that can be implemented on mobile communication devices.

- The first is a real-time motion-based user interface for browsing large images or documents such as maps on small screens. The motion information is extracted from the image sequence captured by the camera.

- The second solution is a real-time panorama builder that uses individual video frames, while

- the third assembles document panoramas, also from single frames.

- The fourth development is a real-time face and eye detector that can be used with autofocusing and red-eye reduction techniques.
