The seriation problem in the presence of a double Fiedler value
Anna Concas, Caterina Fenu, Giuseppe Rodriguez +1
Seriation is a problem consisting of seeking the best enumeration order of a set of units whose interrelationship is described by a bipartite graph, that is, a graph whose nodes ar…
A spectral method for bipartizing a network and detecting a large anti-community
A. Concas, S. Noschese, L. Reichel +1
Relations between discrete quantities such as people, genes, or streets can be described by networks, which consist of nodes that are connected by edges. Network analysis aims to i…
Identifying the lights position in photometric stereo under unknown lighting
A. Concas, R. Dessì, C. Fenu +2
Reconstructing the 3D shape of an object from a set of images is a classical problem in Computer Vision. Photometric stereo is one of the possible approaches. It stands on the assu…
PQSER: A Matlab package for spectral seriation
Anna Concas, Caterina Fenu, Giuseppe Rodriguez
The seriation problem is an important ordering issue which consists of finding the best ordering of a set of units whose interrelationship is defined by a bipartite graph. It has i…
