Consecutive determination of the 4-pixel segment shape number through the rolling window. Two sets of chain code provided HTCC (head to tail) and THCC (tail to head), with their associated local segment CC, also bidirectional: SECC (start to end) and ESCC (end to start), which leads to their derived SESN (start to end) and ESSN (end to start).
