A method may include identifying primly camera speaker coordinates of a location of a speaker relative to a primary camera, converting the primary camera speaker coordinates to secondary camera speaker coordinates, the secondary camera speaker coordinates being of the location and relative to a secondary camera, and adjusting, using the secondary camera speaker coordinates of the secondary camera, a view setting of the secondary camera to track the location of the speaker.

Tracking with multiple cameras

Systems and methods are provided for identifying and displaying whiteboard text and/or an active speaker in a video-based presentation, e.g., a video conference. Video images of an environment including a whiteboard may be captured by a video camera system. The video images may be analyzed to detect at least one text-containing area in the environment. Each text-containing area may be analyzed to determine whether it is an area of a whiteboard. When a text-containing area is identified as a whiteboard area, an area of view including the text-containing whiteboard area may be selected for display, e.g., a subset of the full frame captured by the video system. A video feed from the video camera system may be controlled to display the selected area of view at a client device, to provide a useful view of the whiteboard text and/or a speaking person located near the whiteboard text.

Systems and methods for detection and display of whiteboard text and/or an active speaker

A method may include obtaining a frame of a video stream of multiple video streams of a video conference, obtaining face detection information identifying a face size and a face position of at least one face detected in the frame, and cropping and scaling the frame according to at least one crop and scale parameter using the face detection information to obtain a modified first frame. The at least one crop and scale parameter is based on frames of the multiple video streams. The frames include the frame. The method may further include presenting the modified frame.

Video conference user interface layout based on face detection

A camera shooting program control method, the method is applied to terminal equipment, and the method includes obtaining motion parameters collected by at least one motion sensor in response to a situation that the terminal equipment enters a camera shooting program from a screen locking state, and determining a motion state of the terminal equipment according to the motion parameters collected by the at least one motion sensor; obtaining a mistaken touch rate of a display screen of the terminal equipment in response to the motion state of the terminal equipment being a moving state; and exiting the camera shooting program in response to a condition that the mistaken touch rate is greater than a preset first proportion threshold value.

A method () for operating cameras () in a cascaded network (), comprising: capturing a first view () with a first lens () having a first focal point () and a first centroid (), the first view () depicting a subject (); capturing a second view () with a second lens () having a second focal point () and a second centroid (); detecting a first location of the subject (), relative the first lens (), wherein detecting the first location of the subject (), relative the first lens (), is based on audio captured by a plurality of microphones (); estimating a second location of the subject (), relative the second lens (), based on the first location of the subject () relative the first lens (); selecting a portion () of the second view () as depicting the subject () based on the estimate of the second location of the subject () relative the second lens ().

Optimal view selection in a teleconferencing system with cascaded cameras

A method of tracking a presenter during a videoconference, comprising: detecting, in a data stream, data indicating a presence of one or more persons at a videoconferencing endpoint, the data stream comprising a plurality of frames; detecting tracker initiation data (e.g., that a person is actively talking, or that a person has raised their hand, or both) in the data stream; determining a subject of interest responsive to the tracker initiation data, and tracking the subject of interest as they move while making a presentation.

Tracker activation and deactivation in a videoconferencing system

A videoconferencing endpoint is described that uses a cascading sequence of convolutional neural networks to perform face detection and upper body detection of participants in a videoconference at the endpoint, where at least one member of the sequence of neural networks performs upper body detection, and where the final member of the sequence of neural networks performs face detection based on the results of the upper body detection. The models of the neural networks are trained on both large datasets of faces well as images that have been distorted by a wide-angle camera of the videoconferencing endpoint.

Joint upper-body and face detection using multi-task cascaded convolutional networks

An edge anti-false-touch method is provided. The method includes: obtaining, by a mobile terminal, a face direction of a user of a mobile terminal, and obtaining gesture data of the mobile terminal; determining, by the mobile terminal according to the face direction and the gesture data, a screen display state of the mobile terminal; and adjusting, by the mobile terminal based on the screen display state, a size of an anti-false-touch region of the mobile terminal to trigger an anti-false-touch response of the anti-false-touch region.

Edge anti-false-touch method and apparatus, electronic device and computer-readable storage medium

A method for tracking movement of a presenter during a videoconference comprises tracking the location of subject of interest; quickly detecting error conditions&#x2014;such as can occur when a subject of interest moves too quickly or when a subject of interest walks past another person&#x2014;and quickly reinitiating the tracking sequence to help ensure a positive videoconferencing experience.

Presenter-tracker management in a videoconferencing environment

A method may include receiving a source video frame captured using a wide angle lens, deriving a characteristic of a target video frame from the source video frame, generating a transitional video frame using the source video frame and the target video frame, and transmitting the transitional video frame to an endpoint.
