Static object detection approaches based on selective updating of the background model do not offer a principled way of incorporating such items into the background model.
Table 3 shows that the computational time needed for the update of the state machine is very low compared to the time needed for the update of the background model.
This study does not employ dynamic update of the background model, since the tested video sequences contain minimal ambient lighting change, and for such sequences a one-time construction of a static background model provides reasonable performance.
The volume presents an updated overview of the background ideas of the NEPS and its conceptional framework.
The updating strategy of the background model is given as follows: boldsymbol{alpha}_{i+1} = 1-rho boldsymbol{alpha}}_{i} + rhoboldsymbol{alpha}'_{i}, (1-rho boldsymbol{alpha}
The October 2010 issue of the scientific journal Biomass and Bioenergy contains this article by J. Ruane, A. Sonnino and A. Agostini, which is an abbreviated and updated version of the background document prepared for an e-mail conference hosted by the FAO Biotechnology Forum on the same subject.
The system analyses three interconnected representations of the stereo data to dynamically update a model of the background, to extract foreground objects, such as people and rearranged furniture, and to track their positions in the world.
In the fourth and final phase, background learning and maintenance, the algorithm updates both the background reference image and the tables of feature statistics.
The parameters of the mixtures are updated by changing the buffer of the background values in FIFO order by selective update, and the covariance (in this case, a diagonal matrix) is estimated in the time domain by analyzing the set of differences between two consecutive values.
To summarize the history of the conflict in 2010, and to update the background of the dispute in 2008, the timeline of the nuclear project is described as follows (Ontario Government,2009).
