Video hand image-three-dimensional computer interface with multiple degrees of freedom
InactiveUS6147678AInput/output for user-computer interactionCharacter and pattern recognitionElevation angleImaging processing
A video gesture-based three-dimensional computer interface system that uses images of hand gestures to control a computer and that tracks motion of the user's hand or a portion thereof in a three-dimensional coordinate system with ten degrees of freedom. The system includes a computer with image processing capabilities and at least two cameras connected to the computer. During operation of the system, hand images from the cameras are continually converted to a digital format and input to the computer for processing. The results of the processing and attempted recognition of each image are then sent to an application or the like executed by the computer for performing various functions or operations. When the computer recognizes a hand gesture as a "point" gesture with one or two extended fingers, the computer uses information derived from the images to track three-dimensional coordinates of each extended finger of the user's hand with five degrees of freedom. The computer utilizes two-dimensional images obtained by each camera to derive three-dimensional position (in an x, y, z coordinate system) and orientation (azimuth and elevation angles) coordinates of each extended finger.

InactiveUS20050091311A1Restrict levelPulse modulation television signal transmissionClosed circuit television systemsComputer hardwareClient-side
Video and audio signals are streamed to remote viewers that are connected to a communication network. A host server receives an originating video and audio signal that may arrive from a single source or from a plurality of independent sources. The host server provides any combination of the originating video and audio signals to viewers connected to a communication network. A viewer requests the host server provide a combination of video and audio signals from the host server. The host server transmits an instruction set to be executed by the viewer. The instruction set causes the viewer to transmit parameters to the host user, including parameters relating to the processing capabilities of the viewer. The host server then transmits multimedia data to the viewer according to the received parameters. A plurality of viewers may be simultaneously connected to the host server. Each of the plurality of viewers may configure the received video and audio signals independent of any other viewer and may generate alerts based on the video and audio content.

Systems and methods for semantically classifying shots in video
The present disclosure relates to systems and methods for classifying videos based on video content. For a given video file including a plurality of frames, a subset of frames is extracted for processing. Frames that are too dark, blurry, or otherwise poor classification candidates are discarded from the subset. Generally, material classification scores that describe type of material content likely included in each frame are calculated for the remaining frames in the subset. The material classification scores are used to generate material arrangement vectors that represent the spatial arrangement of material content in each frame. The material arrangement vectors are subsequently classified to generate a scene classification score vector for each frame. The scene classification results are averaged (or otherwise processed) across all frames in the subset to associate the video file with one or more predefined scene categories related to overall types of scene content of the video file.

A video-on-demand (VOD) system is disclosed and method for providing a real-time VOD experience using Tempo-Differential file transfer with various buffering techniques and an adaptive file distribution system. The system is configured to populate users' Set-Top-Boxes (STBs) with a set of videos which correspond to the individual user's preferences, and populates a Central Office Storage (COS) server with a larger set of videos based on an analysis of all of the users' preferences. The system thus provides a real time VOD service by either correctly predicting the videos that a user will request and preloading them onto that user's STB, or by delivering the requested video from the COS to the STB using a Tempo-Differential file transfer which delays the playing of the requested video while video trailers or other information is displayed on the video screen. When using a DSL connection to the COS, only a portion of the requested video needs to be buffered on the STB before the requested video begins playing. Accordingly, by predicting which videos a user will request and by using the Temp-Differential file transfer, a real time VOD experience is achieved.

The processor then determines whether a change in a display characteristic of the PIP leads to the PIP obscuring less of an important portion of the primary display image, and if so, the processor changes the display characteristic of the PIP. Display characteristics of the PIP that may be changed by the processor include the PIP position, size, and transparency. The processor may also utilize a combination of the detected cues to determine important and relatively unimportant portions of the primary display image.
