WebPixels that are black contribute 0 to the average. Thus, to adjust the average to only include non-black pixels, you need to adjust the size you used for smoothing. This adjusted size (actually the scale) is obtained by blurred_mask = cv2.blur (mask). E.g. if you have a 3-by-3 kernel for smoothing and 4 pixels are black, the value at the kernel ...
