It is shown that both changes in viewing position and illumination con(cid:173) ditions can be compensated for, prior to recognition, using combinations of images taken from different viewing positions and different illumina(cid:173) tion conditions. It is also shown that, in agreement with psychophysical findings, the computation requires at least a sign-bit image as input - contours alone are not sufficient.
