Polarization interference optical interleaver

The present patent application relates to a polarization interference optical interleaver, which includes a first port to transmit the first optical signal through the first optical path, a second port to transmit the second optical signal and a third port to transmit the third optical signal. The first optical signal passes through the first optical path and splits into the second optical signal and the third optical signal by the first and the second light splitting/combining crystals and the interference crystal group.

Automatic video editing for real-time generation of multiplayer game show videos

An “automated video editor” (AVE) automatically processes one or more input videos to create an edited video stream with little or no user interaction. The AVE produces cinematic effects such as cross-cuts, zooms, pans, insets, 3-D effects, etc., by applying a combination of cinematic rules, object recognition techniques, and digital editing of the input video. Consequently, the AVE is capable of using a simple video taken with a fixed camera to automatically simulate cinematic editing effects that would normally require multiple cameras and/or professional editing. The AVE first defines a list of scenes in the video and generates a rank-ordered list of candidate shots for each scene. Each frame of each scene is then analyzed or “parsed” using object detection techniques (“detectors”) for isolating unique objects (faces, moving/stationary objects, etc.) in the scene. Shots are then automatically selected for each scene and used to construct the edited video stream.

Real-time Bayesian 3D pose tracking

Systems and methods are described for real-time Bayesian 3D pose tracking. In one implementation, exemplary systems and methods formulate key-frame based differential pose tracking in a probabilistic graphical model. An exemplary system receives live captured video as input and tracks a video object's 3D pose in real-time based on the graphical model.
