Green Image
<p>A constant-time algorithm for labeling the connected components of an N/spl times/Nimage on a reconfigurable network of N/sup 3/ processors is presented. The maincontribution of the algorithm is a novel constant-time technique for determining theminimum-labeled PE in each component. The number of processors used by the algorithm can be reduced to N/sup 2+(1/d/), for any 1/spl les/d/spl les/log N, if O(d) time is allowed.</p>
