Note:

I have available M.Sc. and Ph.D. positions to offer, in a project about machine learning applied to computer vision based large area surveillance. If you are strong in Math, experienced in at least one of MATLAB, C/C++ or Python programming, and most importantly, motivated to work hard, then feel free to contact me with your CV provided that you are interested. If we decide to interview, then please be prepared to answer undergrad-level linear algebra and probability questions.
