摘要： Implementations relate to a computer-implemented method and a device for determining a relative posed between devices. The method can include receiving data representing first keypoint features from a first image captured by a camera of a second mobile computing device; capturing, by a camera of a first mobile computing device, a second image, wherein the first image and the second image comprise a substantially common scene having an area of overlap; computing, by the first mobile computing device, data representing second keypoint features from the second image; determining, by the first mobile computing device, based at least in part on the data representing first keypoint features and the data representing second keypoint features, a relative pose of the first mobile computing device and the second mobile computing device; and communicating the relative pose to the second mobile computing device.

摘要： Implementations relate to a system for video encoding and conversion including an image resolution conversion component operable to convert a resolution of a source image frame from a first resolution to a second resolution to produce a first intermediate image frame at the second resolution; an image conversion component operable to receive the first intermediate image frame and convert an image size of the first intermediate image frame to another image frame size to produce a first viewable image frame; an image viewer component operable to display the first viewable image on a first display; a color space conversion component comprising a luminance conversion component and a chrominance operable to receive the first viewable image frame and convent a first luminance value and a first chrominance value of the first viewable image frame to a second intermediate image frame having a second luminance value and a second chrominance value.

摘要： Disclosed are methods for automatically generating commands to transform a video sequence based on information regarding speaking participants derived from the audio and video signals. The audio stream is analyzed to detect individual speakers and the video is optionally analyzed to detect lip movement to determine a probability that a detected participant is speaking. Commands are then generated to transform the video stream consistent with the identified speaker.

摘要： A method and apparatus for virtual camera operation is disclosed. Virtual camera operation may include identifying potential subjects of a video stream by identifying faces of participants in the input video stream. Virtual camera operation may include determining a speaking state of each participant in the input video stream based on their respective identified face. Virtual camera operation may include identifying a subject of the input video stream based on the speaking state. Virtual camera operation may include generating, using a processor, an output video stream including a portion of the input video stream based on the subject.

摘要： Methods and apparatus for suggesting image, video, and image album titles are presented. A machine-learning service executing on a mobile platform receives feature-related data. The feature-related data includes image-related data related to one or more images received from an application executing on the mobile platform and platform-related data received from the mobile platform. The image-related data and the platform-related data differ. The machine-learning service generates a title related to the one or more images by performing a machine-learning operation on the feature-related data. The machine-learning service sends the title related to the one or more images to the application.
