Extract the pixels in your ROI and then take the mean or std of them using mean/std. If you can provide more information on your ROI that would help us provide a better answer. Is it an IMROI (and children) object? If so you could use its createMask method to generate a mask and the use the mask as a logical index to extract the pixel values...
