Abstract: In this paper, a new approach is proposed for modeling and indexing outline shapes by using simple primitives extracted from the contours of objects. The primitives are line segments and curves described with few bytes of text thanks to use of parametric equations of those primitives. The author also proposes a new and an efficient way to index the outline shapes. Indexes are issued from characteristic polygons determined on the outline shapes of objects. Despite the recognition process is not the aim of their method, the proposed indexing process only is sufficient to retrieve a few most similar models for a given query. Experiments are done on synthetic and real images and give very encouraging results in order to apply the author's approach to the recognition process which will be the next step after this work.
