Hello, Regarding single threaded region growing, the nature of regions growing with a breadth first algorithm is inherently single threaded. However, the equivalent results can be obtained by doing a global threshold, followed by connect components analysis. Both of those algorithms are efficiently multi-threaded. Depending on the size of the image, shape of region, and other factors, one approach may be more efficient than the other.
