| Abstract: | rea correlation algorithms are usually performed using image intensity pixels by pixels,which are not only time-consuming but also lack of robustness to geometrical distortion. A study ismade on an area correlation algorithm using invariant features. Two groups of features, i. e., invariant moments features and concentric circles features, which are invariant in translation, rotation andscale, are proposed. A fast algorithm for invariant moments in binary images is given. The feasibilityof the correlation algorithm is proved by correlation experiments with complex background images. |
