With a second pass at Scene Kit shaping up nicely (i.e. '3D proteins on the table' and friends, release coming shortly!) I've been unable to stop myself from going full steam ahead into Recognition Kit 2: This Time It's For Real.
4K CV pipelines are coming along great, I've got a SIFT prototype functional, and the new shape matching algorithm has begun to introduce its first shapes to each other, so I wanted a peg in the ground on Apriltags to finish the picture... but as I pondered how small we could get the tags... I had to know... just how small of a dot can we actually see at 4K?
To the Print Proofer! First I printed the Realtalk equivalent of a visual acuity test...
Looks like we can see line 3 just fine! (Line 2 is semi-functional with dots flickering in and out, Line 1 is a goner)
Well dang, that looks pretty good. That seems to be right at the theoretical 0.25 scale we should expect from a 1080p -> 4K jump... I wonder... I wonder if...
Now come on that's just silly. There's no way it can see that.
Well... I'll... be. That's the blank, that I wrote the page proof on, to generate a tiny version of itself, being recognized, and generating itself again (complete with tiny little blank page text).
I really thought I'd have to go fix some hardcoded values somewhere the dot frame recognizer, but no, it just works (I'm sure there's something in there to fix though!).
So... ~2x2 postage-stamp-sized fully-fledged Realtalk pages have been apparently been sitting waiting patiently for us since I did the 4K upgrade sometime last year! Amazing.
