METHOD AND SYSTEM FOR REAL TIME MOTION PICTURE SEGMENTATION AND SUPERSOSITION
摘要
Methods and systems for separating a picture part of interest (6) from an arbitrary background (4) in real time videos are presented. The background may be a moving or still frame. The picture part of interest and background frames may be in or out of focus. One separation approach employs the difference between luminance and chrominance values of the input and background frames where changes in luminance from frame to frame are compensated for. In another approach, picture part of interest separation is based solely on spatial resolution differences between the background and the picture part of interest frames. The present invention also teaches a method and system for parameter matching of the picture part of interest and the basic picture into which the picture part of interest is embedded. The invention further teaches a method and system for embedding a separated picture part of interest into a basic picture containing text.
