ABSTRACT:
A digital image is processed to hide information, by generally inconspicuous adjustments of pixel values. Desirably, the processing is adapted to the particular image being encoded, so as to better conceal the encoding. The method may include determining a relative ability of a pixel to be adjusted inconspicuously, by reference to values of at least two neighboring pixels.
