1. An automated method for encoding and graphically embedding digital images into a source image, the method comprising: providing a first digital output image; rasterizing a source image into source image segments having a rasterization frequency equal to or a multiple of a decoder lens frequency; and reforming the rasterized source image segments according to a pattern of the output image to form a revised source image having the output image graphically embedded therein, the out put image being viewable by orienting a decoder with the decoder lens frequency over a printed version of the revised source image.
