[IGSTK-Users] Object Tracking.

[Özgür Güler]

Hi Ashwath,

following steps are involved into object overlay into a scene:

1. detect object on video frame
2. detect correspondent points between detected object and real object.
3. calculate using corresponding points on real object and imaged
object, camera intrinsic parameters, camera distortion coefficients
the pose of the object.

You can do that using ITK and VTK but be aware that you have to build
80 % from scratch.

I would recommend you to use OpenCV for this purpose. The IGSTK video
component implements a web cam video imager using OpneCV. I.e. eather
you ask for new video frames each time the imager has captured a new
videoframe or you modify the igstkWebcamWinVideoImager class to access
the videoframes directly.

Hope this helps,
Özgür
