ABSTRACT

In this paper we present a new method for writing an approximate description of 2D/3D objects in text form using XML language. First, the outline of the shape is divided into parts according to N angular and M radial sectors (or bin), each Bin contains a portion of the contour; this portion is divided at the inflexion points into convex and concave sections and local features are extracted for these partitions, then this features are coded and stored in a XML data structure. In this work we study the possibility of using this textual description in the shape recognition by exploiting the variables and the values stored in the XML file. Experiments on natural silhouette database and MPEG-7 shape databases demonstrate the effectiveness of the proposed method relative to the standard assignment problem.
