ape descriptors performed nearly optimal with re-spect to scaling. The descriptors P298, P320, P517, and P687 correctly retrieved over 99% rotated images in A-2. The performance of P567 (wavelet repre or indicates that it is neither robust to scaling nor to rotation. This result seems to give a clear experimental verification of the known fact
