#3Glad to see some work in this space. While I was doing my PhD all I had was https://datathief.org/, which usually did the job, but had some limitations and was Java-based. Definitely did some manual extraction from time to time.

#4looks great. Although in your example it seems like the y-axis is a bit off.
start: 0.05 vs 0.1
end: 0.65 vs 0.7
It's a difficult example!

#5Great to see new tools in this space. So far we have been using WebPlotDigitizer, it has recently released new versions that stopped being open source but moved to be a paid software, requiring login, plastered with AI advertising terms.

Thanks! Yes, some images have hick-ups. Would probably need a UI that allows for easy post-prediction editing.

Been there too haha! I wanted to do large scale data extraction from literature and manual approaches would have just been too slow.

Most of the time, I just use it to scrape original data from screenshots taken from research papers where the data is not provided as a table. I would say 7/8 of these figures are scatter plots from experimental measurements.
