In this paper: Human Body Tracking by Adaptive Background Models and Mean-Shift Analysis Section 3, the authors mention about luminance ratio thresholds for brightness and darkness (r1, r2). Can anyone suggest what should the values be?

You have them explained in this paper, sections 4.2 and 4.3.

I usually prefer to post self-contained answers, but this topic is not easy to understand without reading the whole paper.

  • Thanks for pointing the paper: [A statistical approach for real-time robust background subtraction and shadow detection](http://academic.research.microsoft.com/Publication/2026552/a-statistical-approach-for-real-time-robust-background-subtraction-and-shadow-detection) ... one doubt: in equation (6) shouldn't it be sqrt(sum of squares) ? – Kaushik Acharya Jun 05 '11 at 09:18
