1. A computer-implemented method for creating a volume, the method comprising: receiving content of a volume at a capturing device; creating, at the capturing device, colored cells within a color space to provide an encoded representation of the received content in an image by processing the received content to obtain a stream of integers, each integer in the stream of integers corresponding to a color in a color space for a cell in the image; creating, at the capturing device, one or more additional cells, including color calibration cells, adjoining the image, the one or more additional cells for assisting in decoding the encoded image, by determining a pseudo-Euclidean metric in the color space, the metric measuring distance including a measure of an average of: (a) a red component in the colored cells and (b) a red component in the color calibration cells; and providing the image on a medium.
