Then, we will analyze its efficiency in respect of the mixture number of the GMM and the combination scheme.
If the mixture number of the GMM increases, then it is preferred that the performance of the VAD will be better.
Four variables are used to characterize the workplace built environment features: population density, land-use mixture, number of road intersections, and proximity to the closest railway station.
Therefore, it is important to find how the mixture number of the GMM will affect the performance and how many mixtures are needed to compromise the detecting time and the accuracy.
