An Efficient and elastic approach for partial shape matching using DTW
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 4
Abstract
We present the Partial shape matching for scale invariant and deformation tolerant 2D images. Scale invariance means a feature of objects that do not change if scale or length of objects changes. Deformation tolerance means tolerating a change in the volume and/or shape of object. We propose to transform shapes into sequences and utilize an algorithm that determines a subsequence of a target sequence that best matches a query.The proposed scheme lies a novel shape descriptor that also permits the quantification of local scale. Shape descriptors are computed along open or closed contours in a spatially non-uniform manner. The resulting ordered collections of shape descriptors constitute the global shape representation. A variant of an existing Dynamic Time Warping (DTW) matching technique is proposed to handle the matching of shape representations. Due to the properties of the employed shape descriptor, sampling scheme and matching procedure, the proposed approach performs partial shape matching that is invariant to Euclidean transformations, starting point as well as to considerable shape deformations.Additionally, the problem of matching closed-toclosed contours is naturally treated as a special case. Algorithm outperforms the commonly used techniques in retrieval accuracy.
