The Precedence of the Work of Said and Pearlman over Ricoh's CREW

As authors of the rst paper we want make clear that, as the rst to publish, we deserve the credit for the discoveries contained on it. Unfortunately, this is necessary because the authors of the CREW paper certainly (as we show below) knew about our work, but failed to yield the smallest recognition. We are aware that simultaneous scienti c discoveries occur all the time. However, it is also well known to us that the euphoria of each new discovery is often followed by the anxiety of thinking: \Haven't anyone published something similar or (God forbid) equal?" The reason for anxiety is that, independently of the brilliance of our derivation, those that published it rst deserve the main credit. This purposeful concealment of information annoyed us because it can only indicate: (i) extreme arrogance; (ii) fear of a fair comparison; (iii) existence of hidden interests; (iv) all above.
