Abstract
Digital video imaging systems and techniques for efficiently transforming warped video images into rectilinear video images, real-time tracking of persons and objects, face recognition of persons, monitoring and tracking head pose of a person and associated perspective view of the person.
Claims34
A system, comprising:
- at least one video camera to capture warped panoramic video images of a scene and to produce a video stream;
- and
- a digital processor to receive and process said video stream, said digital processor comprising:
- a first processing module to unwrap said warped panoramic video images to produce rectilinear video images of the scene, wherein said first processing module provides pan, tilt, and zoom adjustments to allow for customized viewing of the scene, and
- a second processing module to detect and track a person's head in the rectilinear video images and to extract video images in the person's view from the rectilinear video images.

A system, comprising:
- at least one video camera to capture warped panoramic video images of a scene and to produce a video stream;
- a video transmission mechanism to deliver said video stream to a plurality of video receivers, said video transmission mechanism comprising a video server which filters information in said video stream according to security levels assigned to video receivers to produce different filtered video streams to different video receivers;
- and
- a digital processor in each video receiver to independently process said video stream to unwrap said warped panoramic video images to produce rectilinear video images of the scene, said digital processor having a user graphic interface with pan, tilt, and zoom adjustments to allow for customized viewing at each video receiver.

A system, comprising:
- at least one video camera to capture warped panoramic video images of a scene and to produce a video stream;
- and
- a digital processor to receive and process said video stream, said digital processor comprising:
- a first processing module to unwrap said warped panoramic video images to produce rectilinear video images of the scene, wherein said first processing module provides pan, tilt, and zoom adjustments to allow for customized viewing of the scene, and
- a second processing module to extract a face from the streaming rectilinear video images and to perform face recognition on the extracted face.

A system, comprising:
- at least one video camera to capture warped panoramic video images of a scene and to produce a video stream;
- a video transmission mechanism to deliver said video stream to a video receiver;
- and
- a digital processor in said video receiver to process said video stream to unwrap said warped panoramic video images to produce rectilinear video images of the scene,
- wherein said digital processor includes a user graphic interface with pan, tilt, and zoom adjustments to allow for customized viewing of the scene, and said digital processor is operable to superimpose a customized video of the scene over a digital image.
