Figure 5.2. Sample frames from PETS 2001 data setFigure 5.3. Sample frames from PETS 2006 data setOther than the global illumination change at the end of the PETS 2001 data set it is not aterribly difficult data set. There are trees which sway lightly from wind and some foregroundobjects that are off far in the distance. Figure 5.2 contains sample images from the PETS 2001data set.The PETS 2006 data set is the easiest data set of the three. It is in an indoor environment andthe camera is in close proximity to the foreground objects. The largest difficultly is the reflectanceof the floor which causes minor reflections from the foreground objects. Sample frames from thePETS 2006 data set may be found in Figure 5.3.5.3 Parameter SelectionEach of the three data sets were separated into two dichotomic, sequential sets, where onewas used for training/parameter exploration, and the other was used for evaluation. Tables 5.2and 5.3 show the precise splits that were used for each data set. Three parameters exist in the33
