摘要: Abstract The medial loci called cores are generalized maxima in scale space of a form information that is invariant to translation, rotation, and zoom. S. M. Pizeret al.show these invariances imply having the property boundary sensing made with apertures proportional figural width (Comput. Vision Image Understand.69, 1998). This leads an insensitivity image disturbances, strong contrast previously available loci. In particular, disturbances whose amplitude under core's aperture, width, small compared intensity difference figure its background produce only changes position given by core. These insensitivities including additive noise, imaging blur, perturbations, object variations discussed demonstrated here.
