Abstract: Systems and techniques to reduce bandwidth usage of video frames in a videoconferencing system are described. A computing device may receive a first frame of a first video stream from an imaging device and decompose the frame into a plurality of portions. The computing device may select a first portion of the plurality of portions, determine that the first portion matches a sent portion in a sent catalog, determine a first identifier associated with the first portion, and send the first identifier to a server. The computing device may select a second portion of the plurality of portions, determine that the second portion fails to match any of the sent portions in the sent catalog, create and associate a second identifier with the second portion, store the second portion with the second identifier in the sent catalog, and send the second portion to the server.

Abstract: Systems and methods are described to identify in the images text, people, landmarks, objects, or any combination thereof and to store and search for images based on extracted data. A portable computing device, such as a wireless phone or tablet computer, may capture an image, determine context data associated with the image, and send the image and context data to an analyzer. The analyzer may extract data from the image and send the extracted data to the portable computing device. For example, the analyzer may determine if the image includes alphanumeric characters and perform character recognition (e.g., using optical character recognition (OCR) or similar technology). A format of the characters that are recognized in the image may be analyzed to determine additional information, such as whether the characters are a phone number, a uniform resource locator (URL), a name of a person, a name of a location, or the like. The analyzer may determine if the image includes a person, a landmark, an object, etc. by comparing at least a portion of the image with other images. The analyzer may send the extracted data to the portable computing device for storage. The portable computing device may associate the context data and the extracted data with a downsampled (e.g., thumbnail) version of the image to enable a user to query the context data and extracted data.

Abstract: Systems and techniques to dynamically correct a gaze of participants in a video conference are described. A computing device participating in a video conference may determine that a frame of a video stream includes features of a face, extract a portion of the frame that includes a first pair of eyes, and determine that the first pair of eyes are looking in a non-forward direction. The computing device may retrieve, from a database, a stored portion that includes a second pair of eyes that are looking in a forward direction, and modify the frame by substituting the stored portion for the portion in the frame to create a modified frame. The computing device may send the modified frame to a videoconferencing server for distribution to other computing devices participating in the video conference.
