"WebAug 27, 2014 · Original answer: The reason you are getting an array back rather than a single number, is because you haven't specified axis=None in your call to scipy.stats.signaltonoise. Thus, you probably needed this: snr = scipy.stats.signaltonoise (img, axis=None) Without that option, you will get the SNR for every column in the image. " - Signal to noise vs signal to background
