fredrick's solutions seems to be more closer to what I was looking for.But I am still not sure if that could be done without the use of Image module. Also in your solution I cannot follow this [[1, 1, 2, 1, 2, 0], [2, 0, 0, 2, 0, 1], [1, 2, 2, 0, 2, 0], [0, 1, 0, 0, 0, 0], [2, 0, 0, 1, 1, 0], [2, 2, 2, 0, 1, 0]] >>> print "\n".join(str(reg) for reg in getregions(x)) [(0, 1), (0, 0), (0, 2), (1, 0), (0, 3), (2, 0), (1, 3), (0, 4), (2, 1), (3, 1), (2, 2)] [(5, 4), (4, 4), (4, 3)] [(5, 0), (5, 1), (4, 0), (5, 2)] [(1, 5)] [(2, 4)] This is kind of confusing...could you please correlate the grid to the result and explain
