A high resolution means longer image acquisition and larger data requirements for a given sample, but if the resolution is too low, significant information may be lost. This paper studies the impact of changes in resolution on persistent homology, a tool from topological data analysis that provides a signature of structure in an image across all length scales. Given prior information about a function, the geometry of an object, or its density distribution at a given resolution, we provide methods to select the coarsest resolution yielding results within an acceptable tolerance. We present numerical case studies for an illustrative synthetic example and samples from porous materials where the theoretical bounds are unknown.","lang":"eng"}],"main_file_link":[{"url":"https://arxiv.org/abs/2111.05663","open_access":"1"}],"type":"conference","day":"13","month":"01","article_processing_charge":"No","date_updated":"2023-08-02T14:44:21Z","quality_controlled":"1","title":"The impact of changes in resolution on the persistent homology of images","status":"public","oa":1,"oa_version":"Preprint","date_created":"2022-03-06T23:01:53Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publisher":"IEEE","scopus_import":"1"}
