Where to find Camshift + Kalman Filter samples?

edit

You can just take a look at the supplied C++ samples that come with openCV

OpenCV\samples\cpp\camshiftdemo.cpp
OpenCV\samples\cpp\kalman.cpp

I think this is the best starting point for a solution.

There are also plenty tutorials on the net when using google like:

• http://imranakthar.com/android-opencv-tutorial-3-face-tracking-using-camshift-histogram/
• http://jayrambhia.wordpress.com/2012/07/11/face-tracking-with-camshift-using-opencvsimplecv/

Take a look at this project: camshift-kalman-examples. It contains various projects using a combination of camshift and kalman filters for tracking.

1. Camshift using Hue only (with Kalman filter)
2. Camshift using Hue only (with Kalman filter)
3. Camshift using Hue and Value (with Kalman filter)
4. Camshift using Hue and Local Binary Patterns (with Kalman Filter)
