The theoryof the gradient based structure tensor (a.k.a. the secondmoment matrix) is a very well suited theoretical platform inwhich to analyze and explain the similarities and connections(indeed often equivalence) of supposedly different methodsand features that deal with image directionality. Of specialinterest to this study is the SIFT descriptors (histogram oforiented gradients, HOGs). Our analysis of interrelationshipsof prominent directionality analysis tools offers thepossibility of computation of HOGs without binning, in analgorithm of comparative time complexity.</p> SSBA 2010 Symposium i bildanalys, Uppsala 11-12 mars http://hh.diva-portal.org/smash/record.jsf?searchId=1&pid=diva2:391385 Conference Paper Directionality Features and the Structure Tensor 2010 2014-03-13T11:50:18Z 2456729.9932639 Directionality Features and the Structure Tensor 500 0 plainlist list 1 [[:Publications:Directionality Features and the Structure Tensor]] Directionality Features and the Structure Tensor# QUERYa42da93101512d89ead056301a15e3b4 500 [2,"smw-datavalue-property-restricted-annotation-use","Author"] Directionality Features and the Structure Tensor# ERRe24f17e090c98448f3de99d03182b7b6
