How about this:

dice = 2*nnz(segIm&grndTruth)/(nnz(segIm) + nnz(grndTruth))

This expects segIm and grndTruth to be of the same size. They must also be numeric or logical.

I don't understand. segIm is what he called your final segmented image - your final binary image after all processing has been done. What do you mean by "how to put is that whole image"? There is nothing to put, it is just a variable. And you stick the variable into the equation.
