??? Error using ==> iptcheckinput Function BWMORPH expected its first input, BW, to be two-dimensional.

Error in ==> bwmorph at 77 iptcheckinput(a,{'numeric' 'logical'},{'real' 'nonsparse' '2d'}, ...

I'll go ahead and throw out the obvious, ensure that 'bw2' is a 2-dimensional numeric matrix. http://www.mathworks.com/help/toolbox/images/ref/bwmorph.html

For example, you may need to use im2bw() to convert a color image to black and white.
