Re: [Vxl-users] How to use VXL in Visual C++ to track a face realtime?

[Junaed S. <ju...@ci...>]

I have not used VXL for face tracking, but I have done extensive visual
tracking research and the implementation is all built on VXL (since
2005). I have had absolutely no performance issues, so I'd think it
would  be quite possible to build a face tracker with VXL (of course the
specific algorithm used for the face tracker would be the major
contributor in CPU consumption).

FYI, my tracker implementations (C++/VXL) run on a "real" amphibious
robot that uses visual tracking as part of a human-robot interface
framework. I'm personally very pleased with VXL. OpenCV is another
option, as it is now well-supported by a robotics company, but at the
time I started, it was in not so great shape, and I see no compelling
reason to move away from VXL.

Junaed
