Robustness of a multiscale scheme of feature points detection

We present a new scheme for feature points detection on a grey level image. I:ts principle is the study of the gradient phase signal along object edge s and the characterization of the behavior across scales of the wavelet coe fficients of this signal. The features points are determined as transition points of this signal. In the second part, we study the robustness of the d etection scheme against changes of the acquisition parameters: the viewpoin t and the zoom of the camera, the object rotation, the luminescence variati on and noise. The results show the method efficiency: most of the points ar e still detected even if these parameters vary. (C) 2000 Pattern Recognitio n Society. Published by Elsevier Science Ltd.
