Augmented reality implementation method

A method for implementing a personalized augmented reality associated to carrier means, wherein said method comprises:

• receiving at input an optical image (1) of said carrier means;
• incorporating an information content in said optical image (1) in such a way that said information content is hidden in said optical image (1), where said information content is customizable (102);
• decoding said information content (103);
• and
• reproducing said information content through an electronic device, wherein said reproduction enables implementation of said augmented reality;
• said method envisaging, after said incorporation and prior to said decoding, the step of transferring said optical image (1) onto said carrier means, wherein the latter may comprise a physical medium, in particular in the form of paper or fabric, or else a digital medium, such as a display of an electronic device,
• said method being characterized in that said incorporation of the information content in said optical image (1) comprises:
• receiving at input said information content (102.1);
• if said optical image (1) is not square, rendering said optical image square (102.2) so as to obtain a square image (2);
• transforming said square image (2) with the discrete Fourier transform (102.3) to obtain a transformed square image (3), wherein said transformed square image (3) is formed by a first, magnitude-matrix, channel and by a second, phase-matrix, channel;
• generating a plurality of data matrices (D), wherein each of said matrices is a binary square matrix (104A, 104B);
• dividing each of said data matrices (D) into two triangular semi-matrices (D1, D2) (102.4);
• introducing each of said triangular semi-matrices (D1, D2) within said first, magnitude-matrix, channel of said transformed square image (3) (102.5) at a distance (d, d) from the constant Fourier coefficient to obtain a modified first, magnitude-matrix, channel (M′), said distance (d, d) varying in a predefined way for each pair of triangular semi-matrices (D1, D2), in such a way that each pair of semi-matrices does not overlap with the other pairs of semi-matrices during the step of introduction into said modified first, magnitude-matrix, channel M′;
• and
• after said introduction, carrying out the inverse transform of said modified first, magnitude-matrix, channel (M′) together with said second, phase-matrix, channel to obtain said optical image in which said information content has been incorporated.
