Brazilian Symposium on Computer graphics and Image Processing (sibgrapi)
作者: Raissa T. Vieira Carlos Eduardo de Oliveira Chierici Carolina T. Ferraz Adilson Gonzaga Department of Electrical Engineering University of São Paulo São Paulo Brazil Universidade de Sao Paulo Sao Paulo São Paulo BR
this paper proposes a new methodology for micro pattern analysis in digital images based on fuzzy numbers. A micro-pattern is the structure of the gray-level pixels within a neighborhood and can describe the spatial c... 详细信息

24th sibgrapi conference on graphics, patterns and images
作者: Günther, David Reininghaus, Jan Hotz, Ingrid Wagner, Hubert Zuse Institute Berlin Berlin Germany Institute of Computer Science Jagiellonian University Krakow Poland
We propose a memory-efficient method that computes persistent homology for 3D gray-scale images. the basic idea is to compute the persistence of the induced Morse-Smale complex. Since in practice this complex is much ... 详细信息
