Define density. Isn't it just the pixel value, like
pixelValue = grayImage(row, column);
Please see my image segmentation tutorial and other demos: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
And what does parzen (your tag) have to do with anything?

I am not sure what you mean, but if it is the intensity of a pixel, you can access that as follows:
gives you the intensity of pixel 50,60 in 'yourimage'.
If you want to know the pixel density of your image, you need to know the number of pixels in your image along each dimension and the 'real' size of your image along each dimension.
