hi if I have an array
say x = [[2,2,0,0,1,1],
[1,1,0,0,1,1],
[1,1,0,0,1,1]]
I basically want to group regions that are non zero like I want to get
the coordinates of non zero regions..as (x1,y1,x2,y2)
[(0,0,2,1),(0,4,2,5)] which show the top left(x1,y1) and bottom
right(x2,y2) corners of each group.hope i am clear.Thanks -- http://mail.python.org/mailman/listinfo/python-list
