<p>An encoding method is provided. The encoding method includes a mapping for mapping a plurality of encoding sequences, each of which includes at least one encoding symbol chosen from an encoding symbol set, to a plurality of decoding sequences, each of which includes at least one decoding symbol chosen from a decoding symbol set. The encoding method is characterized in that at least one of the encoding sequences includes at least two encoding symbols, and a predetermined shape changing type of a formal symbol in the encoding sequence is denoted by a latter symbol neighboring to the formal symbol, wherein the shape changing type including at least one of shape rotating, shape mirroring, shape deflating, stroke removal, cutting and notching.</p> |
