On a new method of watermark embedding in an audio signal

In the paper a two-stage algorithm of allocation of contours bitmap images has been considered. At the first stage fragments of contours in four various directions come to light. This stage is a stage lost-free as it is based on arithmetics on the module 2Q. At the second stage fragments of contours are united in the general contour of the image. This stage is a stage with losses as it is based on nonlinear real arithmetics. The example of allocation of contour bitmap images has been shown.
