Abstract: Various embodiments of separating a picture part of interest from an arbitrary background are described. 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 on spatial resolution differences between the background and the picture part of interest frames. Parameter matching can also be performed for the picture part of interest and the basic picture into which the picture part of interest is embedded. Further, a separated picture part of interest can be embedded into a basic picture containing text.
