Optimal change point detection and localization in sparse dynamic networks [PDF]
, 2021 We study the problem of change point localization in dynamic networks models. We assume that we observe a sequence of independent adjacency matrices of the same size, each corresponding to a realization of an unknown inhomogeneous Bernoulli model.

Spatial attention is attracted in a sustained fashion toward singular points in the optic flow. [PDF]
PLoS ONE, 2012 While a single approaching object is known to attract spatial attention, it is unknown how attention is directed when the background looms towards the observer as s/he moves forward in a quasi-stationary environment.

Singular points detection with semantic segmentation networks
CoRR, 2019 Singular points detection is one of the most classical and important problem in the field of fingerprint recognition. However, current detection rates of singular points are still unsatisfactory, especially for low-quality fingerprints. Compared with traditional image processing-based detection methods, methods based on deep learning only need the ...

Robust Hole-Detection in Triangular Meshes Irrespective of the Presence of Singular Vertices [PDF]
, 2023 In this work, we present a boundary and hole detection approach that traverses all the boundaries of an edge-manifold triangular mesh, irrespectively of the presence of singular vertices, and subsequently determines and labels all holes of the mesh.

An Enhanced Incremental SVD Algorithm for Change Point Detection in Dynamic Networks
IEEE Access, 2018 Change point detection is essential to understand the time-evolving structure of dynamic networks. Recent research shows that a latent semantic indexing (LSI)-based algorithm effectively detects the change points of a dynamic network.

Finger image quality based on singular point localization [PDF]
, 2014 Singular points are important global features of fingerprints and singular point localization is a crucial step in biometric recognition. Moreover the presence and position of the core point in a captured fingerprint sample can reflect whether the finger
