2013-2017 PhD at University of La Rochelle (L3I/MIA), France. 2014-2015 (3+3 months) PhD research stage at Computer Vision Center (CVC), Barcelona, Spain. 2010-2012 MSc in Mechatronics Engineering - Federal University of Bahia, Brazil. 2004-2009 BSc in Computer Engineering at AREA1 Engineering School, Brazil. Academic background: --------------------------------- I'm currently conducting my doctoral research to apply advanced matrix and tensor tools for robust video analysis (i.e. background modeling and subtraction, image and video classification, video action recognition, online and incremental learning). Keywords: Robust PCA (RPCA), Non-negative Matrix/Tensor Factorization (NMF/NTF), Low-rank Matrix/Tensor Approximation, Low-rank Representation (LRR), Incremental SVD/HoSVD, Subspace Clustering, Compressed Sensing and Sparse Representation. My interest also includes intelligent video analytics such as: object detection, segmentation and tracking, crowd analysis and motion analysis for event/action recognition and behavior classification. I've worked also on several embedded systems and robotics projects using micro-controllers and SoC boards to read sensors, I/O devices, making data acquisition, signal processing, image/video processing, wireless communication and motor control.
