Quick context: SR-as-a-pre-filter for ALPR gets a lot of attention right now there's a whole ICPR 2026 competition track on low-res plate recognition; so we actually testing it on our production lpr data.

Have you tried classic CV SR algorithms (eg SR from multiple nearby frames)? Single frame SR seems unlikely to be useful.

We tried that, wasn't a big lift to setup and tested. We used 1000 detections with at least 4 crops, and it made a bit of a difference but not much - our conclusion remains the same.

No, that is a really great point. The ICPR competition the big winners were all about multi-frame. Will do some more experiments and update.

Yah we should probably add some back, we had examples but they were mostly meaningless to the human eye, but we'll try adding some "examples"
