Talk: Leveraging Spatial, Spectral and Temporal Features for Spoofing Detection in Images and Videos
Being part of a series of four talks that will be given at NTU Singapore, in this second talk Prof. Anderson Rocha (RECOD) will explore the research field of Spoofing Detection in Images and Videos. Abstract: Recent advances on biometrics, … Continue reading
A graph-based ranked-list model for unsupervised distance learning on shape retrieval
Several re-ranking algorithms have been proposed recently. Some effective approaches are based on complex graph-based diffusion processes, which usually are time consuming and therefore inappro- priate for real-world large scale shape collections. In this article, the authors present a novel … Continue reading
A correlation graph approach for unsupervised manifold learning in image retrieval tasks
In this paper, the authors Daniel Pedronette and Ricardo Torres, discuss a novel unsupervised manifold learning algorithm, which aims at imitating the human behavior in judging similarity among images. The proposed algorithm exploits unlabeled contextual information encoded in the dataset … Continue reading
