ABSTRACT:
Systems and methods are provided through which a template in the spatial domain is generated and combined with an image. Later, the combined image can be decoded to determine the extent of scaling and or shifting or the combined image. The template comprises at least one vertical or horizontal band. The horizontal band(s) determine the extent of scaling and/or shifting along the vertical axis, and the vertical bands determine the extent of scaling and/or shifting along the horizontal axis of the combined image. Using both horizontal and vertical bands enables decoding of shifting and scaling along both axis, and creates a grid. Each band specifies a predetermined characteristic of modifying the luminance of the corresponding pixels of the image. In one alternative, the modification of the image is performed to the extent that the bands are invisible to the naked eye.
