Florez http://www.omarflorez.info/index.php?id=homepage&rev=1320774762&do=diff Currently I am doing my Ph.D. in Computer Science at Utah State University. I did internships with IBM Research in 2010 and 2011. I was born in Peru and came to the US to work as a Research Assistant in projects on Data Mining, Pattern Recognition, and Computer Vision. Specifically, I have been working on Traffic Understanding in Video Sequences, Clustering and Indexing of Unstructured Data (Videos, Music, and Human Motion), Multimedia Information Retrieval, Large Scalable Systems, and Real-tim… text/html 2011-09-15T20:03:56-05:00 Omar U.
