 I used different kernels for the variance.  The first set of plots below use the variance * kern^2^, which is equivalent to convolving with a kernel 1/sqrt(2) times the sigma of image.  This is the mathematically correct method.  The second set of plots use the variance * kern, where the same kernel is used on the image as is on the variance.  This is not the mathematically correct method, but probes the space of "what if we convolve the variance incorrectly".
