Broadly speaking, such criteria are divided into intrinsic and extrinsic, the first referring to the metric structure of the objects and the latter to the geometry of the shapes in the Euclidean space. Both criteria have their advantages and disadvantages; extrinsic similarity is sensitive to non-rigid deformations of the shapes, while intrinsic similarity is sensitive to topological noise. Here, we present an approach unifying both criteria in a single distance. Numerical results demonstrate the robustness of our approach in cases where using only extrinsic or intrinsic criteria fail.","lang":"eng"}],"language":[{"iso":"eng"}],"title":"Rock, paper, and scissors: Extrinsic vs. intrinsic similarity of non-rigid shapes","type":"conference","_id":"18389","day":"30","author":[{"last_name":"Bronstein","first_name":"Alexander","full_name":"Bronstein, Alexander","id":"58f3726e-7cba-11ef-ad8b-e6e8cb3904e6","orcid":"0000-0001-9699-8730"},{"full_name":"Bronstein, Michael M.","last_name":"Bronstein","first_name":"Michael M."},{"full_name":"Kimmel, Ron","last_name":"Kimmel","first_name":"Ron"}],"publication_identifier":{"issn":["1550-5499"],"isbn":["9781424416301"]},"date_updated":"2024-11-18T10:12:46Z","fulldoi":"https://doi.org/10.1109/iccv.2007.4409076","scopus_import":"1"},{"volume":72,"citation":{"mla":"Raviv, Dan, et al. “Symmetries of Non-Rigid Shapes.” <i>11th International Conference on Computer Vision</i>, vol. 72, IEEE, 2007, doi:<a href=\"https://doi.org/10.1109/iccv.2007.4409181\">10.1109/iccv.2007.4409181</a>.","chicago":"Raviv, Dan, Alex M.

Since many natural objects are symmetric, the absence of symmetry can often be an indication of some anomaly or abnormal behavior. Therefore, detection of asymmetries is important in numerous practical applications, including crystallography, medical imaging, and face recognition, to mention a few. Conversely, the assumption of underlying shape symmetry can facilitate solutions to many problems in shape reconstruction and analysis. Traditionally, symmetries are described as extrinsic geometric properties of the shape. While being adequate for rigid shapes, such a description is inappropriate for non-rigid ones. Extrinsic symmetry can be broken as a result of shape deformations, while its intrinsic symmetry is preserved. In this paper, we pose the problem of finding intrinsic symmetries of non-rigid shapes and propose an efficient method for their computation."}],"title":"Symmetries of non-rigid shapes","language":[{"iso":"eng"}],"status":"public","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"}]
