摘要： A panoramic camera design that is lower cost, robust, stable and more user friendly than prior art designs. The camera design makes use of a unified molded structure of optical material to house a mirror, aligned sensor, and lens assembly. The unified molded structure of the camera keeps the sensed optical path enclosed to minimize dust and user's fingers and maintain optical alignment.

摘要： Provided herein are systems, methods, and software for facilitating a video conference environment. In at least one implementation, video captured of a scene is received. A modification to display of the video is identified based at least in part on a share of a display space associated with an object in the scene relative to a share of another display space associated with another object in another scene. The modification to the display of the video is then initiated. In another implementation, the modification may also be based on a target share indicated by way of an interactive graphic.

摘要： Provided herein are systems, methods, and software for facilitating collaboration environments. In at least one implementation, a presentation of an initial view of a collaboration scene is presented within a collaboration environment. A portion of the collaboration scene is identified that corresponds to an object of interest selected for separate viewing. A separate presentation within the collaboration environment is initiated related to the portion of the scene corresponding to the object of interest.

摘要： A gradient-corrected linear interpolation method and system for the demosaicing of color images. The method and system compute an interpolation using some a current technique (preferably a bilinear interpolation technique to reduce computational complexity), compute a correction term (such as a gradient of a desired color at a given pixel), and linearly combine the interpolation and the correction term to produce a corrected, high-quality interpolation of a missing color value at a pixel. The correction term may be a gradient correction term computed from the current color of the current pixel. This gradient is directly used to affect and correct the estimated color value produced by the prior art interpolation technique. The gradient-corrected linear interpolation method and system may also apply a gradient-correction gain to the gradient correction term. This gradient-correction gain affects the amount of gradient correction that is applied to the interpolation.

摘要： A system and method for detecting speech utilizing audio and video inputs. In one aspect, the invention collects audio data generated from a microphone device. In another aspect, the invention collects video data and processes the data to determine a mouth location for a given speaker. The audio and video are inputted into a time-delay neural network that processes the data to determine which target is speaking. The neural network processing is based upon a correlation to detected mouth movement from the video data and audio sounds detected by the microphone.

摘要： Systems and methods for maintaining orientation of a non-cylindrical panorama is described wherein an initial magnetometer reading is obtained for a panoramic camera. If the panoramic camera is rotated from an initial position, a new magnetometer reading is obtained and a magnitude of rotation is determined. The magnitude of rotation is factored into an image stitching and warping process to create a panoramic image that maintains the initial orientation.

摘要： An automated system and method for broadcasting meetings over a computer network. The meeting is filmed using an omni-directional camera system and capable of being presented to a viewer both live and on-demand. The system of the present invention includes an automated camera management system for controlling the camera system and an analysis module determining the location of meeting participants in the meeting environments. The method of the present invention includes using the system of the present invention to broadcast an event to a viewer over a computer network. In particular, the method includes filming the event using an omni-directional camera system. Next, the method determines the location of each event participant in the event environment. Finally, a viewer is provided with a user interface for viewing the broadcast event. This user interface allows a viewer to choose which event participant that the viewer would like to view.

摘要： A system and process for highlighting the current speaker on an on-going basis in each frame of a low frame-rate video of an event having multiple people in attendance is presented. In general, this is accomplished by periodically identifying an attendee that is currently speaking at a rate substantially faster than the video frame rate, and updating each frame of the video to highlight the current speaker. More particularly, an A/V source provides a video stream to a client computing device that includes delta frames interspersed between the frames of the low frame-rate video. The full video frames act as keyframes, and the delta frames provide the changes needed to modify the last displayed version of the last keyframe to highlight just the region associated with the location of a current speaker. This allows the client device to operate as a standard A/V rendering and display unit.
