This paper discusses how it can be exploited for people surveillance in very cluttered environments in terms of perspective (i.e., weak scene calibration) and appearance of the objects of interest (i.e., relevance feedback on the training of a classifier).
Camera sensitivity variation measured using a 57Co sheet source was small and had a weak relationship to calibration factor variations.
Surprisingly, the disc's weak spot is its calibration routines, which ought to be a cakewalk.
The model showed a moderate discriminative power (C-Statistic: 0.74), whereas calibration was weak (p Hoshmer-Lemeshow test = 0.006).
Calibration was a weak link: too little blood into Gregory, and his oxygen-starved brain would waste away; too much, and the pressure would cause tissue swelling, also potentially fatal.
However, as shown in Figure 7, the presence of weak noise with the same calibration error value as in the previous figure, produce a significant performance degradation and the two methods become equivalent.
Considering the absolute value, the fiberoptic catheter, after 12 hours of usage without any further calibration, presented a weak accuracy.
On the other hand, the empirical equations proposed in this context generally produce weak simulations, except when a local calibration is used for improving their performance.
Thus, strain-rate calibration is required for weak shales such as those studied here to appropriately estimate physical properties under in situ conditions.
However, a perfect trending ability together with a weak accuracy would essentially indicate that further calibration would solve the problem.
With this knowledge, optimal calibration methods can be chosen and weak points in the machine tool design can be identified systematically.
