We generalize this notion to the mid-sphere axis, which consists of all points for which the Euclidean distance function has two interchanging saddles that swap their partners in the pairing by persistent homology. It offers a discrete-algebraic multi-scale approach to computing ridge-like structures on the surface. As a proof of concept, an algorithm that computes stair-case approximations of the mid-sphere axis is provided."}],"author":[{"first_name":"Herbert","orcid":"0000-0002-9823-6833","last_name":"Edelsbrunner","full_name":"Edelsbrunner, Herbert","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Stephenson","full_name":"Stephenson, Elizabeth R","id":"2D04F932-F248-11E8-B48F-1D18A9856A87","first_name":"Elizabeth R","orcid":"0000-0002-6862-208X"},{"full_name":"Thoresen, Martin H","last_name":"Thoresen","id":"47CB1472-F248-11E8-B48F-1D18A9856A87","first_name":"Martin H"}],"_id":"20658","doi":"10.1007/978-3-032-09544-2_10","publication":"4th International Joint Conference on Discrete Geometry and Mathematical Morphology","OA_type":"green","article_processing_charge":"No","date_created":"2025-11-23T23:01:37Z","alternative_title":["LNCS"],"year":"2025","publisher":"Springer Nature","language":[{"iso":"eng"}],"arxiv":1,"oa":1,"external_id":{"arxiv":["2504.14743"]},"volume":16296,"publication_status":"published","department":[{"_id":"HeEd"}],"date_published":"2025-11-01T00:00:00Z","OA_place":"repository","status":"public","intvolume":"     16296","scopus_import":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"conference"}
