Fast Parallel Thinning Algorithms: Parallel Speed and Connectivity Preservation

  title={Fast Parallel Thinning Algorithms: Parallel Speed and Connectivity Preservation},
  author={Richard W. Hall},
  journal={Commun. ACM},
A recently published parallel thinning approach [4] is evaluated. An improvement is suggested to enable preservation of certain diagonal lines which are not preserved by this algorithm. A unified notion of what is meant by an iteration (or subiteration) and parallel speed is presented, and with regard to its parallel speed this algorithm is argued to be comparable to other two-subiteration algorithms. The parallel speed of this algorithm is compared experimentally to the original algorithm that… CONTINUE READING
