Video hand image-three-dimensional computer interface with multiple degrees of freedom

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.

Multiple remote display system

A multi-display system includes a host system that supports both graphics and video based frames for multiple remote displays, multiple users or a combination of the two. For each display and for each frame, a multi-display processor responsively manages each necessary aspect of the remote display frame. The necessary portions of the remote display frame are further processed, encoded and where necessary, transmitted over a network to the remote display for each user. In some embodiments, the host system manages a remote desktop protocol and can still transmit encoded video or encoded frame information where the encoded video may be generated within the host system or provided from an external program source. Embodiments integrate the multi-display processor with either the video decoder unit, graphics processing unit, network controller, main memory controller, or any combination thereof The encoding process is optimized for network traffic and attention is paid to assure that all users have low latency interactive capabilities.

Method and apparatus for distributing multimedia to remote clients

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.

Blending a graphic

A graphic and video are blended by controlling the relative transparency of corresponding pixels in the graphic and the video through the use of blending coefficients. One example of a blending coefficient is an alpha signal used in conjunction with a keyer. The value of a blending coefficient for a pixel in the graphic is based on the luminance and chrominance characteristics of a neighborhood of pixels in the video. Inclusions and exclusions are set up which define how the neighborhood of pixels is used to create or change a particular blending characteristic.

Methods and interfaces for event timeline and logs of video streams

Techniques for generating timelines and event logs from one or more fixed-position cameras based on the identification of activity in the video are presented. Various embodiments of the invention include an assessment of the importance of the activity, the creation of a timeline identifying events of interest, and interaction techniques for seeing more details of an event or alternate views of the video. In one embodiment, motion detection is used to determine activity in one or more synchronized video streams. In another embodiment, events are determined based on periods of activity and assigned importance assessments based on the activity, important locations in the video streams, and events from other sensors. In different embodiments, the interface consists of a timeline, event log, and map.

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.
