Independent Units in an Array

Question

An array (let 20*20) inputs either B or W. Imagine the array to be the grids of a graph paper. B implies that grid (let 4*5) be black in colour and W means the grid is white in colour. The compiler categories each black grid as one unit. If multiple black grids occur adjacent to each other (only top bottom left and right)(diagonally not counted) , be it in the shape of rectangle or square or maybe T shaped, the complete structure is counted as one unit. So the program has to find how many such black independent units are there.
