These diagrams encode persistent homology, a widely used invariant in topological data analysis. While several avenues towards a statistical treatment of the diagrams have been explored recently, we follow an alternative route that is motivated by the success of methods based on the embedding of probability measures into reproducing kernel Hilbert spaces. In fact, a positive definite kernel on persistence diagrams has recently been proposed, connecting persistent homology to popular kernel-based learning techniques such as support vector machines. However, important properties of that kernel enabling a principled use in the context of probability measure embeddings remain to be explored. Our contribution is to close this gap by proving universality of a variant of the original kernel, and to demonstrate its effective use in twosample hypothesis testing on synthetic as well as real-world data."}],"main_file_link":[{"url":"https://papers.nips.cc/paper/5887-statistical-topological-data-analysis-a-kernel-perspective","open_access":"1"}],"volume":28,"acknowledgement":"This work was partially supported by the Austrian Science FUnd, project no.

Depending on the type of representation, the simplification of the Morse-Smale complex works differently. In the explicit representation, the Morse-Smale complex is directly simplified by explicitly reconnecting the critical points during the simplification. In the implicit representation, on the other hand, the Morse-Smale complex is given by a combinatorial gradient field. In this setting, the simplification changes the combinatorial flow, which yields an indirect simplification of the Morse-Smale complex. The topological complexity of the Morse-Smale complex is reduced in both representations. However, the simplifications generally yield different results. In this chapter, we emphasize properties of the two representations that cause these differences. We also provide a complexity analysis of the two schemes with respect to running time and memory consumption.","lang":"eng"}],"day":"19","doi":"10.1007/978-3-319-04099-8_9","year":"2014","citation":{"ama":"Günther D, Reininghaus J, Seidel H-P, Weinkauf T.

The HKS is derived from the heat kernel and was originally introduced as an isometry invariant shape signature. Each positive definite tensor field defines a Riemannian manifold by considering the tensor field as a Riemannian metric. On this Riemmanian manifold we can apply the definition of the HKS. The resulting scalar quantity is used for the visualization of tensor fields. The HKS is closely related to the Gaussian curvature of the Riemannian manifold and the time parameter of the heat kernel allows a multiscale analysis in a natural way. In this way, the HKS represents field related scale space properties, enabling a level of detail analysis of tensor fields. This makes the HKS an interesting new scalar quantity for tensor fields, which differs significantly from usual tensor invariants like the trace or the determinant. A method for visualization and a numerical realization of the HKS for tensor fields is proposed in this chapter. To validate the approach we apply it to some illustrating simple examples as isolated critical points and to a medical diffusion tensor data set.","lang":"eng"}],"day":"19","publication_identifier":{"issn":["1612-3786"],"eissn":["2197-666X"],"eisbn":["9783319040998"],"isbn":["9783319040981"]},"doi":"10.1007/978-3-319-04099-8_16","status":"public","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","acknowledgement":"This research is partially supported by the TOPOSYS project FP7-ICT-318493-STREP.","author":[{"full_name":"Zobel, Valentin","last_name":"Zobel","first_name":"Valentin"},{"id":"4505473A-F248-11E8-B48F-1D18A9856A87","full_name":"Reininghaus, Jan","last_name":"Reininghaus","first_name":"Jan"},{"first_name":"Ingrid","last_name":"Hotz","full_name":"Hotz, Ingrid"}],"scopus_import":"1","publication":"Topological Methods in Data Analysis and Visualization III ","_id":"10886","month":"03","title":"Visualization of two-dimensional symmetric positive definite tensor fields using the heat kernel signature","alternative_title":["Mathematics and Visualization"],"article_processing_charge":"No","department":[{"_id":"HeEd"}],"date_created":"2022-03-18T13:05:39Z","oa_version":"None","publication_status":"published","language":[{"iso":"eng"}],"quality_controlled":"1","page":"249-262","publisher":"Springer"},{"publication_identifier":{"isbn":["9783319130743"],"issn":["0302-9743"],"eissn":["1611-3349"],"eisbn":["9783319130750"]},"type":"conference","date_published":"2014-11-08T00:00:00Z","related_material":{"record":[{"id":"481","relation":"later_version","status":"public"}]},"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"None","month":"11","publication":"25th International Symposium, ISAAC 2014","conference":{"name":"ISAAC: International Symposium on Algorithms and Computation","start_date":"2014-12-15","location":"Jeonju, Korea","end_date":"2014-12-17"},"language":[{"iso":"eng"}],"day":"08","doi":"10.1007/978-3-319-13075-0_10","abstract":[{"lang":"eng","text":"In this paper, we introduce planar matchings on directed pseudo-line arrangements, which yield a planar set of pseudo-line segments such that only matching-partners are adjacent.

Nevertheless, there is currently no efficient algorithm to robustly extract these features. In this chapter, we present a novel technique to extract saddle periodic orbits. Exploiting the analytic properties of such an orbit, we propose a scalar measure based on the finite-time Lyapunov exponent (FTLE) that indicates its presence. Using persistent homology, we can then extract the robust cycles of this field. These cycles thereby represent the saddle periodic orbits of the given vector field. We discuss the different existing FTLE approximation schemes regarding their applicability to this specific problem and propose an adapted version of FTLE called Normalized Velocity Separation. Finally, we evaluate our method using simple analytic vector field data.","lang":"eng"}],"doi":"10.1007/978-3-319-04099-8_4","day":"19","date_updated":"2022-06-21T12:01:47Z","citation":{"mla":"Kasten, Jens, et al. “Toward the Extraction of Saddle Periodic Orbits.” <i>Topological Methods in Data Analysis and Visualization III </i>, edited by Peer-Timo Bremer et al., vol. 1, Springer, 2014, pp. 55–69, doi:<a href=\"https://doi.org/10.1007/978-3-319-04099-8_4\">10.1007/978-3-319-04099-8_4</a>.","short":"J.

The embedding process may result in a change of the topology of the input data, e.g., by introducing self-intersections, which is undesirable or even disastrous for many applications. In this paper we present a watermarking framework for two-dimensional vector graphics that employs conventional watermarking techniques but still provides the guarantee that the topology of the input data is preserved. The geometric part of this framework computes so-called maximum perturbation regions (MPR) of vertices. We propose two efficient algorithms to compute MPRs based on Voronoi diagrams and constrained triangulations. Furthermore, we present two algorithms to conditionally correct the watermarked data in order to increase the watermark embedding capacity and still guarantee topological correctness. While we focus on the watermarking of input formed by straight-line segments, one of our approaches can also be extended to circular arcs. We conclude the paper by demonstrating and analyzing the applicability of our framework in conjunction with two well-known watermarking techniques.","lang":"eng"}],"volume":24,"acknowledgement":"Work by Martin Held and Stefan Huber was supported by Austrian Science Fund (FWF): L367-N15 and P25816-N15.","ddc":["000"],"scopus_import":1,"_id":"1816","issue":"1","author":[{"id":"4700A070-F248-11E8-B48F-1D18A9856A87","first_name":"Stefan","last_name":"Huber","orcid":"0000-0002-8871-5814","full_name":"Huber, Stefan"},{"first_name":"Martin","last_name":"Held","full_name":"Held, Martin"},{"full_name":"Meerwald, Peter","last_name":"Meerwald","first_name":"Peter"},{"first_name":"Roland","last_name":"Kwitt","full_name":"Kwitt, Roland"}],"department":[{"_id":"HeEd"}],"date_created":"2018-12-11T11:54:10Z","publication_status":"published","intvolume":"        24","pubrep_id":"443","title":"Topology-preserving watermarking of vector graphics","quality_controlled":"1","page":"61 - 86","file_date_updated":"2020-07-14T12:45:17Z","publisher":"World Scientific Publishing","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"type":"journal_article","date_published":"2014-03-16T00:00:00Z","oa":1,"publist_id":"5290","file":[{"file_id":"4704","creator":"system","relation":"main_file","access_level":"open_access","date_updated":"2020-07-14T12:45:17Z","content_type":"application/pdf","file_name":"IST-2016-443-v1+1_S0218195914500034.pdf","date_created":"2018-12-12T10:08:43Z","checksum":"be45c133ab4d43351260e21beaa8f4b1","file_size":991734}],"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","status":"public","has_accepted_license":"1","publication":"International Journal of Computational Geometry and Applications","oa_version":"Published Version","month":"03","language":[{"iso":"eng"}]},{"issue":"1","author":[{"first_name":"Josef","last_name":"Cibulka","full_name":"Cibulka, Josef"},{"full_name":"Gao, Pu","last_name":"Gao","first_name":"Pu"},{"last_name":"Krcál","first_name":"Marek","full_name":"Krcál, Marek","id":"33E21118-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Tomáš","last_name":"Valla","full_name":"Valla, Tomáš"},{"full_name":"Valtr, Pavel","last_name":"Valtr","first_name":"Pavel"}],"scopus_import":1,"publication":"Discrete & Computational Geometry","_id":"1842","intvolume":"        53","title":"On the geometric ramsey number of outerplanar graphs","month":"11","date_created":"2018-12-11T11:54:18Z","department":[{"_id":"UlWa"},{"_id":"HeEd"}],"oa_version":"Submitted Version","publication_status":"published","language":[{"iso":"eng"}],"page":"64 - 79","publisher":"Springer","type":"journal_article","date_published":"2014-11-14T00:00:00Z","year":"2014","citation":{"chicago":"Cibulka, Josef, Pu Gao, Marek Krcál, Tomáš Valla, and Pavel Valtr. “On the Geometric Ramsey Number of Outerplanar Graphs.” <i>Discrete &#38; Computational Geometry</i>.
