Figure 1: Training stage. From left to right: mapping func- func-tion of the 3D-models, extracfunc-tion of closed curves, the  col-lection of all curves to define the bag-of-features and the quantize features vector.
Figure 4 presents the Precision vs Recall curves for the whole dataset of our bag-of-feature technique and of the  in-dexed closed curve method
Figure 5: Partial 3D-models.
