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.

(segIm&grndTruth) :
segIm = image that we wanna reference with
grndTruth = image that being reference
just determine what is segIm and grndTruth after you obtain them, just concatenate them (segIm&grndTruth)
