While a close relation between (i) and (ii) might phenomenologically not be unexpected, our work appears to be the first to make this connection precise for one dimensional signals. We provide a link between (i) and (ii) that builds on the equivalence between TV‐L2 regularization and taut strings and leads to a novel and efficient denoising algorithm that is contrast preserving and operates in O(nlogn) time, where n is the size of the input."],["dc.identifier.doi","10.1063/1.3497795"],["dc.identifier.gro","3146525"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/4308"],["dc.language.iso","en"],["dc.notes.intern","mathe"],["dc.notes.status","public"],["dc.notes.submitter","chake"],["dc.publisher","American Institute of Physics"],["dc.publisher.place","Melville, NY"],["dc.relation.eventend","2010-09-25"],["dc.relation.eventlocation","Rhodes"],["dc.relation.eventstart","2010-09-19"],["dc.relation.isbn","978-0-7354-0835-7"],["dc.relation.ispartof","Numerical analysis and applied mathematics"],["dc.subject","Total variation topological persistence denoising"],["dc.title","Total Variation Meets Topological Persistence: A First Encounter"],["dc.type","conference_paper"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]
