Wei Wang, Yan Yan, Feiping Nie, Xavier Alameda-Pineda, Shuicheng Yan and Nicu Sebe . Abstract: Graph based dimensionality reduction techniques have been successfully applied to clustering and classification tasks. The fundamental basis of these algorithms is the constructed graph ...

Silèye Ba, Xavier Alameda-Pineda, Alessio Xompero and Radu Horaud Abstract: Object tracking is an ubiquitous problem that appears in many applications such as remote sensing, audio processing, computer vision, ...

We 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 ...

We will be giving a tutorial at ACM Multimedia’2016: Emerging topics in learning from noisy and missing data. The tutorial will be given on October the 16th in collaboration with  Dr. Timothy Hospedales, Prof. Elisa Ricci, Prof. Xiaogang Wang and Prof. Nicu Sebe. The abstract reads below. While vital for handling most computer vision problems, collecting ...

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) ...

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 ...

I presented a paper with the title: Recurrent Face Aging at CVPR’16, because Wei and Nicu could not make it to Las Vegas. Someone actually recorded the talk, so while waiting for the official videos, you can get part of the oral presentation here:

I will be giving a seminar at Télécom ParisTech on June the 7th the abstract of which reads below. 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 that many researchers invested efforts into developing computational approaches ...

I will be giving a seminar at INRIA, CMU and IRI on computer vision applications of matrix completion. Matrix completion is a generic framework aiming to recover a matrix from a limited number of (possibly noisy) entries. In this content, low-rank regularizers are often imposed so as to find matrix estimators that are robust to noise ...

Dionyssos Kounades-Bastian, Laurent Girin, Xavier Alameda-Pineda, Sharon Gannot and Radu Horaud The separation of moving sound sources is a challenging task mainly because it is extremely complex to devise algorithms that robustly discriminate those signal variations due to the intrinsic variation of the sound source from those signal variations due to the time-varying ...
