Let me explain in simple terms.

We explained our technology to a person in charge of a financial institution and he understood it.
He said he felt pretty good when he understood.

There is one pen on the desk.
Take a picture of this pen and remember this as the image of a good pen.
Then you take a picture of another pen, and if it is the same, it is a good pen, and if there is any difference, it is a bad pen.
Glamichan" makes this determination for the front and back sides at high speed.

It does not have to be a pen. It is only an inspection to see if the images are the same.
There is no need to think about what a defect looks like. If they are different from the good ones, they are all defective.
If only 70% of the items are the same as the good items, only the remaining 30%, "something different from the good items," need to be inspected by a person.
The advantage of automation is that this sorting of good products can be done many times faster than by a human operator.

That's the basics, the rest is a bonus. There is nothing difficult about it.
