Thales Vieira


I am Professor at the Institute of Mathematics, UFAL, Maceió, Brazil. I am currently interested in Geometric Modeling and Pattern Recognition.
Lately my research has been focused on real-time gesture recognition using depth sensors like Microsoft Kinect. You can find my lattes curriculum here.
