The NUC process should be repeated whenever the output image
becomes spatially noisy as shown in the left image in Figure 3-5. The
output can become spatially noisy when the environmental temperature
changes (such as from day to night operation and vice versa). NUCs
should be performed to align the sensitivities of the individual pixels as
shown in the right picture. This will enable optimum detection and
recognition.
