measure only. It may be
noticed that SIFT-based feature achieved better results that SURF-based features:
they have higher
RV
values and slightly better stabilities. Comparing grey level-
based versions with the opponent colour-based ones it is seen that the latter are
significantly better, especially in terms of stability, and their rankings are also better
in general.
