bwlabel_test is available in a MATLAB version and an Octave version and a Python version.
components, a Python code which seeks the connected nonzero or nonblack components of an image or an integer array.
percolation_simulation, a Python code which simulates a percolation system. A rectangular region is decomposed into a grid of MxN squares. Each square may be porous or solid. We are interested in a path of porous squares connecting the top and bottom, or the left and right boundaries. The original MATLAB code was written by Ian Cooper.
