Verification

At recovering time, the vision system described in section (2) is used to extract several local surfacepatches of the object. Local regions presenting high curvature are chosen to be reconstructed first becausein such regions angular distribution and curvatures are more discriminative and are relatively easy cheap nike shoes in the hash table (Ababsa, Roussel, Mallem, & Didier, 2002). For each reconstructed surfacepatch, the angular distribution and curvatures are computed. These values are compared to the ones storedin the model data base, if a correspondence occurs, a surface patch recognition hypothesis is thengenerated. The verification module allows to discard false recognition cheap Wholesale nike shoes . For each generatedhypotheses, the corresponding geometric transformation is computed, and then the model surface patchesare back projected onto the image plane. Buy cheap nike shoes
