- drpossum 2y agoGlad to see some work in this space. While I was doing my PhD all I had was https://datathief.org/ 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.
- tdsone3 2y agoBeen there too haha! I wanted to do large scale data extraction from literature and manual approaches would have just been too slow.
- zurfer 2y agolooks 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!
- tdsone3 2y agoThanks! Yes, some images have hick-ups. Would probably need a UI that allows for easy post-prediction editing.
- chazeon 2y agoGreat 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. https://automeris.io/ https://automeris.io/
- tdsone3 2y agoWould be interested in your use case if you don't mind sharing!
- chazeon 2y agoMost 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.
