Abstract
In this paper, based on the advantages of both optical transmission and electronic computation, we first provide an O(log log N) bus cycles parallel algorithm for weighted distance transforms of an N×N binary image on a linear array with a reconfigurable pipelined bus system using N 2 processors. By increasing the number of processors, the proposed algorithm can be run in O(loglog q N) and O(1) bus cycles using qN 2 and N 2 + 1/ε processors respectively, where \(2 \leq q \leq \sqrt{N}, \varepsilon\) is a constant and ε ≥ 1. These results improve on previously known algorithms developed on various parallel computation models.
