We show that the matched filter proposed by Ribak for extending the weighted-shift-and-add method does in fact reduce photon-statistics dominated specklegrams. The iterative method for arriving at the matched filter, as originally proposed by Ribak, does not converge in the case of photon-noisy specklegrams for objects with more than one maxima. Methods for making the procedure more "artificially intelligent" are discussed.
