Claim 5:
6. The computer implemented method for detecting a marker embedded in an image or video content according to claim 1, wherein the method further comprises:
g) receiving an input image or frame for detection;
h) parsing the input image or frame by groups of pixels aligned along an image parsing direction, pixels of each pixel group being separated within the image in the image parsing direction by a number of pixels equal to a size of pixel blocks, groups of pixels having a size of a number of bit sequences in the header part;
i) in each group of pixels, detecting a color of each pixel, and matching said color with one of encoding colors of a bit sequence; and
j) comparing resulting pairs of bit sequences to pairs of bit sequences of the header part taking into account their positions and, upon detecting a chosen number of matching pairs of bit sequences, storing a position of a first pixel in a corresponding group of pixels as a potential marker starting position.
