Abstract: A method and system for use of obfuscation coding. An example method includes a computing system receiving an image that depicts a human face. The method then includes the computing system generating a modified image based on the received image, with the generating of the modified image involving inserting into the received image an obfuscation marker that (i) obfuscates the human face in a manner that prevents a person observing the modified image from identifying the human face and (ii) includes predefined symbology that is interpretable by a machine to identify the obfuscated human face. Further, the method includes using the predefined symbology in the modified image as a basis to take action based on an identity of the human face.

Abstract: In one aspect, an example method includes (i) receiving audio from a first client device engaged in a communication session with a second client device, the audio comprising one or more words spoken by a user of the first client device; (ii) using the audio and a facial feature model to estimate facial movement that corresponds to the one or more words spoken by the user; (iii) generating a synthetic video depicting an avatar of the user moving according to the estimated facial movement; and (iv) in response to generating the synthetic video, causing the second client device to present the synthetic video synchronized with the audio.

Abstract: In one aspect, a method includes receiving video content comprising a first data portion comprising parameters that control a visual appearance of frames of video content presented by a content-presentation device. The content-presentation device is communicatively coupled to a light unit that is (i) present in a viewing area of the content-presentation device and (ii) configured to provide ambient light in the viewing area. The method also includes extracting, from the received video content, a second data portion, separate from the first data portion, specifying one or more light control parameters that a controller associated with the light unit is configured to interpret as instructions for controlling the light unit. The method also includes transmitting the extracted second data portion to the controller to facilitate the controller controlling the light unit according to the specified one or more light control parameters.

Abstract: In one aspect, an example method includes (i) obtaining first media content; (ii) obtaining plot data associated with the obtained first media content; (iii) obtaining user profile data associated with a user; (iv) identifying from the obtained first media content, a first set of segments; (v) using at least the obtained plot data, the obtained user profile data, and segment data associated with each segment, to determine segment relevance data for each such segment; (vi) using at least the determined segment relevance data for the segments as a basis to select, from among the identified first set of segments, a second set of segments; (vii) using at least the selected second set of segments to generate second media content, wherein the generated second media content is shorter in duration than the obtained first media content; and (viii) outputting for presentation the generated second media content.

Abstract: In one aspect, an example method includes (i) estimating, using a skeletal detection model, a pose of an original actor for each of multiple frames of a video; (ii) obtaining, for each of a plurality of the estimated poses, a respective image of a replacement actor; (iii) obtaining replacement speech in the replacement actor's voice that corresponds to speech of the original actor in the video; (iv) generating, using the estimated poses, the images of the replacement actor, and the replacement speech, synthetic frames corresponding to the multiple frames of the video that depict the replacement actor in place of the original actor, with the synthetic frames including facial expressions for the replacement actor that temporally align with the replacement speech; and (iv) combining the synthetic frames and the replacement speech so as to obtain a synthetic video that replaces the original actor with the replacement actor.
