Aiming at the characteristics of the contour-curve′s normalized rear-axes-angle and multi-scale description of the Wavelet Descriptor, this paper proposes a delaminating image retrieval model by using R-tree index, which hierarchically filter the similar templates with the object pattern via the multi-resolution description techniques of the contour to ensure the system′s efficiency and precisi.
