One final note about the PE algorithm: it is very aggressive. It can pull detail out of very low contrast
imagery. It can also greatly enhance some very low-level NUC and FPA artifacts and noise if the
contrast is low enough. This does not necessarily mean there is a problem with either the camera or
the NUC.
5.6.1 AGC ROI Settings
The AGC ROI Settings panel allows the user to define a box region. Only the pixels within the box will
be used to calculate the AGC coefficients. This is particularly useful if there is part of the scene that is
much higher or lower in intensity than the target of interest. The ROI is defined by entering the size
and position directly in the parameter fields or the user can use the mouse to drag the corners of the
green box to create the desired rectangular region. The default is that the AGC ROI is not enabled, in
which case the panel controls are grayed out:
When Enable AGC ROI is on, the panel controls can be accessed. The user can change the size and
position of the box. At this point, the Apply button will not be grayed out. When the user hits the Apply
button, the changes are made and the apply button grays out again. The Show When Enabled control
makes the ROI visible on the SDI video as an overlaid rectangular frame.
