Example: Image Window Positioned Around Blisters
When you have properly positioned the image window, pick Continue to go
to the next step (or pick Stop to abort the auto setup process at this point).
Learn Background Color
When you pick Continue , the system automatically begins the process of
“learning” the background color as Color 1 . The term “background color”
applies to the color of the blister package, not including the pockets or the
objects (tablets or capsules), which are considered to be in the foreground.
The learning process requires several seconds to complete. While it is under
way, its progress is reported in the help message box. As the system
continues to learn the background color, the color parameters are continually
updated and displayed in the message box, as follows:
Learning Background Color
–26 < H < 40 6 < S < 70 94 < I < 218
The changing numbers on the bottom line reflect the hue, saturation, and
intensity values as they are automatically calculated.
A green outline appears around each “object” that the system determines to
be a discontinuity or “hole” in the background color. (These “objects” are
mostly the tablets or capsules that are the subjects of the inspection; or, when
aluminum blisters are used, they are mostly pockets. The green outlines
could also include some “noise” objects at this stage, but the system will
ignore them when learning the object colors if they are less than half the size
