A. Appendix, Implementation For example, the parameter T of GMM is described as follows: ? Name: T ? Value: P min = 0.2, P max = 0.8, ? = 0.05. ? Error indicator: I noise ? Preference: Low With this interface, the two tuning algorithms can work with various background subtraction algorithms. We have tested these tuning algorithms with EGMM and GMM. For the contex-based parameter tuning method to tune the parameters of the background subtraction algorithm EGMM to detect strong shadow in outdoor scenes, we are developing and have not nished it yet. We will nish this functionality in the near future, Bibliography [ATON ] ATON. Project ATON, vol.170, pp.161-169
