摘要： A method comprising: displaying a UI for display of received video; detecting selection of a UI button; receiving a plurality of drawing inputs while the button is selected, each drawing input defining image data to be applied at a facial position on a first side of a face of a user displayed in the received video; for each drawing input, determining a further facial position on a second side of the face, that is symmetrically opposite to the facial position; and for each received video frame, the method comprises: for each drawing input (i) determining a position of the face in the frame by executing an algorithm to determine the locations of the facial position and determined further facial position on the face in the frame; and (ii) applying the image data to the facial position and the determined further facial position; and displaying the modified frame in the UI.

摘要： A computer implemented method can decode a frame of video data comprising an array of pixels to obtain decoded luma values and decoded chroma values corresponding to the array of pixels, and extract a frame mask based on the decoded luma values. The frame mask can include an array of mask values respectively corresponding to the array of pixels. A mask value indicates whether a corresponding pixel is in foreground or background of the frame. The method can perform a morphological operation to the frame mask to change one or more mask values to indicate their corresponding pixels are removed from the foreground and added to the background of the frame. The method can also identify foreground pixels after performing the morphological operation to the frame mask, and render a foreground image for display based on the decoded luma values and decoded chroma values of the foreground pixels.

摘要： Techniques are described for efficiently embedding frame masks in a video stream. In some solutions, a computer implemented method includes operations for encoding a frame of video data comprising an array of pixels to generate an encoded video frame and transmitting the encoded video frame. The array of pixels can include foreground pixels and background pixels. The foreground pixels can have respective original luma values which are bounded within a first luma range. In certain examples, encoding the frame of video data can include converting the original luma values of the foreground pixels to updated luma values which are bounded within a second luma range. The second luma range can be shifted and/or compressed from the first luma range.
