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： Frames containing audio data may be received, the audio data having been derived from a microphone array, at least some of the frames containing residual acoustic echo after having acoustic echo partially removed therefrom. Probability distribution functions are determined from the frames of audio data. A probability distribution function comprises likelihoods that respective directions are directions of sources of sounds. An active speaker may be identified in frames of video data based on the video data and based on audio information derived from the audio data, where use of the audio information as a basis for identifying the active speaker is controlled by determining whether the probability distribution functions indicate that corresponding audio data includes residual acoustic echo.

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.
