Most important in automated visual inspection

This much is clear.
It must be easy for those who use it in the field!
If it is not easy, it cannot be used.
If it is not easy to use, there will be no effect.
Even for an inspection system with low detection capability,
If it is easy to use and can detect only the most serious defects, the introduction of the system is effective.
However, whether there is a return on investment is a mystery.
I don't think it is possible to make image processing technology easy to use at the field level.
I also think it is impossible to say the least.
Perhaps the more advanced the technology becomes, the more it will be removed from the field.
Unless we can break out of this spiral, I don't think automated visual inspection will become widespread.
