Automated Card Grading - Surface

[kevinlenane]

I should also note - that the actual surface grade is basically learned behavior and is a somewhat proportional measure of how far the card diverges from the perfect version and then also the extent of each diversion. And even a 10 or 100% will have significant diversions/anomalies.

We touched on this a little in the CSG grading thread.

Dam Kevin - I had been thinkin that I was a fairly innovative "IT" guy.

You're on a whole different level than the rest of us nerds - KUDOS bud!

Come on! Pls don't bring AI to our hobby. We all love our beat up T cards, using AI grading them, they will all come back as 1s.

The machine vision is capable of detecting the set, year and card and then can adjust its surface parameters and level of acceptance accordingly. This enables a more accurate and consistent score and also enables better fingerprinting though this isnt necessarily required for that unique identification of the cards given how unique each card is.

Oddly enough normalizing the perspective from the many possible/variable camera angles proved to be almost as difficult a solution vs. working out this surface adjustment.
