k = imread('2.jpg');
img2=rgb2gray(k);
sigma =?;
mu=?
pd = makedist('Normal',mu,sigma);
data = img2(I,j)

My theory is that you are trying to fit a Normal Distribution to a histogram of the gray levels. http://www.mathworks.com/help/stats/histfit.html but also http://www.mathworks.com/matlabcentral/answers/44962#answer_55073
