  • ICPR’16 tutorial on multimodal human behavio… August 9th, 2016 ICPR'16 tutorial on multimodal human behavior analysis in the wildWe will be giving a tutorial at ICPR’2016 on “Multimodal Human Behaviour Analysis in the Wild:Recent Advances and Open Problems” together with Elisa Ricci and Nicu Sebe. Abstract: The automated analysis of human behavior in unstructured scenarios has many potential applications in health care, conflict and people management, sociology, marketing and surveillance. It is therefore unsurprising ...

While vital for handling most computer vision problems, collecting ...
  • Sketch-based image retrieval @ ACMMM’16 … July 12th, 2016 Sketch-based image retrieval @ ACMMM'16 & ICPR'16 Dan Xu, Xavier Alameda-Pineda, Jingkuan Song, Elisa Ricci and Nicu Sebe In the last few years, the query-by-visual-example paradigm gained popularity, specially for content based retrieval systems. As sketches represent a natural way of expressing a synthetic query, recent research efforts focused on developing algorithmic solutions to address the sketch-based image retrieval (SBIR) ...
  • Remote heart-rate estimation with self-adaptive ma… June 29th, 2016 Remote heart-rate estimation with self-adaptive matrix completion @ CVPR'16 (Las Vegas) Sergey Tulyakov, Xavier Alameda-Pineda, Elisa Ricci, Lijun Yin, Jeffrey Cohn and Nicu Sebe Recent studies in computer vision have shown that, while practically invisible to a human observer, skin color changes due to blood flow can be captured on face videos and, surprisingly, be used to estimate the heart rate (HR). While considerable progress has been ...
