The authors explained the chart, it only works because it looks across the whole chart for similar parts and recreates the smaller characters using the data it finds in the larger ones. So you would need a couple larger images of the licence plate too.
Information cannot be created from nothing, the algorithm sees that the chart seems to be repeating a similar image over and over, so it guesses the best fit for those images on the bottom lines. They might even be completely wrong, for example, is it really a D and not an O?
- ricardobeat 14y agoYes. That's why the author mentions using other plate images from the time, having the same typeface, to seed the algorithm. He mentions that higher res photographs exist, which might yield a plate image of a similar resolution to that chart's smallest characters. He is not asking for magic, and it's obviously not "creating information from nothing". No one here is stupid. It's "matching low-density patterns to correlated high-density ones", which you already know if you read the article. Maybe there isn't enough data at all to do it - I don't have access to these images to know better, but that doesn't make the idea any less reasonable.
