Abstract: A system and method for object tracking using probabilistic mode-based multi-hypothesis tracking (MHT) provides for robust and computationally efficient tracking of moving objects such as heads and faces in complex environments. A mode-based multi-hypothesis tracker uses modes that are local maximums which are refined from initial samples in a parametric state space. Because the modes are highly representative, the mode-based multi-hypothesis tracker effectively models non-linear probabilistic distributions using a small number of hypotheses. Real-time tracking performance is achieved by using a parametric causal contour model to refine initial contours to nearby modes. In addition, one common drawback of conventional MHT schemes, i.e., producing only maximum likelihood estimates instead of a desired posterior probability distribution, is addressed by introducing an importance sampling framework into MHT, and estimating the posterior probability distribution from the importance function.

Abstract: A combined digital and mechanical tracking system and process for generating a video using a single digital video camera that tracks a person or object of interest moving in a scene is presented. This generally involves operating the camera at a higher resolution than is needed for the application, and cropping a sub-region out of the image captured that is output as the output video. The person or object being tracked is at least partially contained within the cropped sub-region. As the person or object moves within the field of view of the camera, the location of the cropped sub-region is also moved so as to keep the subject of interest within its boundaries. When the subject of interest moves to the boundary of the FOV of the camera, the camera is mechanically panned to keep the person or object inside its FOV.

Abstract: A method of digitally adding the appearance of makeup to a videoconferencing participant. The system and method for applying digital make-up operates in a loop processing sequential video frames. For each input frame, there are typically three general steps: 1) Locating the face and eye and mouth regions; 2) Applying digital make-up to the face, preferably with the exception of the eye and open mouth areas; and 3) Blending the make-up region with the rest of the face. In one embodiment of the invention, the background in the frame containing a video conferencing participant can also be modified so that other video conferencing participants cannot clearly see the background behind the participant in the image frame. In one such embodiment of the invention, the video conferencing participant tries to make his or her own image look comical or altered. In another embodiment of the invention, a particular remote participant tries to make another participant look funny to the other participants.

Abstract: A system and process for finding the location of a sound source using direct approaches having weighting factors that mitigate the effect of both correlated and reverberation noise is presented. When more than two microphones are used, the traditional time-delay-of-arrival (TDOA) based sound source localization (SSL) approach involves two steps. The first step computes TDOA for each microphone pair, and the second step combines these estimates. This two-step process discards relevant information in the first step, thus degrading the SSL accuracy and robustness. In the present invention, direct, one-step, approaches are employed. Namely, a one-step TDOA SSL approach and a steered beam (SB) SSL approach are employed. Each of these approaches provides an accuracy and robustness not available with the traditional two-step approaches.

Abstract: Audio/video programming content is made available to a receiver from a content provider, and meta data is made available to the receiver from a meta data provider. The meta data corresponds to the programming content, and identifies, for each of multiple portions of the programming content, an indicator of a likelihood that the portion is an exciting portion of the content. In one implementation, the meta data includes probabilities that segments of a baseball program are exciting, and is generated by analyzing the audio data of the baseball program for both excited speech and baseball hits. The meta data can then be used to generate a summary for the baseball program.

Abstract: A system for communicating audio data signals comprises a source computer that performs an action, generates an event message corresponding to the action, converts the event message into an audio data signal, and communicates the audio data signal through its speaker. A source telephone receives a voice signal from a participant and the audio data signal through its microphone and communicates the audio data signal and voice as coherent sound via an audio communications medium. A recipient telephone receives the audio data signal from the coherent sound communicated via the audio communications medium and communicates the audio data signal via its speaker. A recipient computer receives the audio data signal through its microphone, extracts the event message from the audio data signal, and performs an action based on the event message from the audio data signal. The audio communications medium can comprise a telephone communications system or air.

Abstract: Automatic detection and tracking of multiple individuals includes receiving a frame of video and/or audio content and identifying a candidate area for a new face region in the frame. One or more hierarchical verification levels are used to verify whether a human face is in the candidate area, and an indication made that the candidate area includes a face if the one or more hierarchical verification levels verify that a human face is in the candidate area. A plurality of audio and/or video cues are used to track each verified face in the video content from frame to frame.
