Abstract
Disclosed are a method and apparatus for embedding a graphic image representation into a two dimensional matrix code by modifying the characteristic values of individual pixels in the image according the values of a provided two dimensional matrix code image. The modified character pixel values are determined using an optimization procedure that minimizes a visual distortion with respect to the original graphic image representation while maintaining the value of a probability of error model below a specified limit.
