Hi Kevin, question for you: how does your normalization not affect the pixel vectors of the original scan? Given it probably affects the values you have for raw images ( assuming you're not reducing dimensions). Question 2: how do you deal with different size/complexity of scans to "grade"? seems like they could be all different size vectors. Super cool work

Great video. I wish you the best and hope to see this being used ASAP to grade cards.

Here's a question. Is your scanning effective if a card is already graded and sitting in a slab? Because it would be really cool if you were able to scan 10, 20, 50, whatever, different graded examples of the very same card where each received the exact same grade (say PSA 7), and were able to tell which ones were 'accurately' (for lack of a better word) graded and which were not. It'd be a helluva interesting undertaking. Of course, you would need a lot of volunteers to send you their cards.

Everybody loves a distribution! The big question is skewed-left or skewed-right.

Automated grading - full subgrades
 

Hey all - so we've managed to get the remaining sub-grades implemented and we have it working well in head-to-heads with human graders within an average of .23 their sub-grade averages. Next step is building out additional set support and modern set support before building the API and/or mobile app.

Definitely getting exciting - we'll have some additional unique features including visual sub-grade justification which will put to rest any accuracy questions. I dont have the business model or distribution figured out just yet but we have some strong first moves in mind.

Nice update. Interested to see where this goes. Please don't let someone buy the technology just to bury it.

The overlay feedback is going to be, as the kids say, lit.

Very exciting.

In light of todays announcement....
 

Figured it was time to pop this thread to the top.

Congratulations Kevin!

Hey Kevin - I'm sure you're still watching over your baby and this thread also, so was wondering...

Could you give us an update on the progress of your work?

I understood how what you were developing would assist in recognizing a card's issue, measuring size for the standard, identifying damage to the surface and being able to do things like scan for alterations such as recoloring.

Is there a method you happened upon that would with certainty identify trimming, specifically as it has been described as being of assistance in the PSA linked articles?

To me, that is the biggest of the fraud alterations that cause the most angst and is hardest to say 100% has occurred because it's possible to make edges appear 'non fresh'.
We as hobbyists often make the assumption on what seems likely, but I feel grading companies fall more heavily on the side of what can they prove and be 100% positive in calling out.

Appreciate any new thoughts you might add to what we could be expecting as part of PSA purchasing your work.
