Daniel Lelis Baggio started his work in computer vision through medical image processing at InCor (Instituto do Coracao – Heart Institute) in Sao Paulo, where he worked with intravascular ultrasound image segmentation. Since then, he has focused on GPGPU and ported the segmentation algorithm to work with NVIDIA's CUDA. He has also dived into 6degrees of freedom head tracking with a natural user interface group through a project called ehci (http://code.google.com/p/ehci/).He now works for the Brazilian Air Force.
