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.

but how to put segIm image value is that whole image

Image Analyst on 26 Mar 2013

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.
