Abstract
A method of generating a readable matrix code image encoding a message based on an input image and a readable matrix coding specification, comprising: calculating function areas readable to comply with a function patterns specification; determining an extent of free cells and derived cells according to a code word specification; calculating decode input values for free cells such that the appearance of the free cells compared to respective areas of the input image complies with a visual perceptual similarity criterion and with the code word specification; and calculating decode input values for derived cells based on the free cells decode input values and in compliance with the code word specification.
Claims10
A computerized method of generating a readable two-dimensional code encoding a message based on an input image, the two-dimensional code including function patterns and cells, the method comprising:
- calculating the function patterns;
- and
- calculating decoded values for the cells based on at least the encoded message, such that an appearance of a portion of the cells complies with a visual similarity criterion when compared with respective areas of the input image associated with the portion of the cells.
