You can get the values using the createMask method of any imroi object.

This will give you the pixel values in the mask (where the mask is true):
pixelValues = grayImage(mask);
Also, see my attached masking demo, and see my Image Segmentation Tutorial in my File Exchange: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862&sort=downloads_desc
