Dictionary
Dictionary/Set of markers, it contains the inner codification BytesList contains the marker codewords where: - bytesList.rows is the dictionary size - each marker is encoded using nbytes = ceil(markerSize*markerSize/8.) - each row contains all 4 rotations of the marker, so its length is 4*nbytes bytesList.ptr(i)[k*nbytes + j] is then the j-th byte of i-th marker, in its k-th rotation.
