Abstract
A method, system and computer program for defining a geometric code is provided. The method for generating a geometric code includes the steps of defining a first geometric shape, defining a size of a second geometric shape as a change in size from the first geometric shape, defining a position of the second geometric shape as a change in position from the first geometric shape, and displaying the first geometric shape and the second geometric shape. A system for imaging the defined geometric code includes a processor performing the steps of segmenting the imaged code, partitioning the segmented imaged code, determining a gray level of each portion of the partitioned segmented imaged code, and determining a code represented by each segmented portion of the partitioned segmented imaged code.
