Help with surface descriptors!

Hi there,

first of all I am an amateur imageJ user.

I need to come up with a variable (measurement) that can tell part the two attached images. These are yeast cells that have or don't have a high gray value close to the center of the cell.

   

I looked at the kurtosis but this is not enough as sometimes cells have high gray values on the edges and that results in an increased kurtosis value.

The plot surface for the two types of cells (peak near the center OR no peak/peak on the edges of cell) enhances the differences between these two groups but I don't know how to get descriptive numbers out of the plots.

Any help/comments?
