Abstract
Technologies relating to system and method of real-time video overlaying or superimposing display from multiple mutually synchronous cameras are disclosed. An example method of real-time video overlaying includes the steps of: synchronizing frame rates of a depth data, a face meta data, and a video data of a first camera video output captured by a first camera; determining a first depth between a user face and the first camera; using a cutoff depth to determine a user body contour; generating a binary mask of the user body contour based on the first depth and the cutoff depth; smoothing an edge of the binary mask; merging the binary mask with the first camera video output and generating a merged first camera video output; and overlaying the merged first camera video output onto a second camera video output.
