Acuna DE, Brookes PS, Kording KP. Bioscience-scale automated detection of figure element reuse. bioRxiv 2018 Feb. 22
(doi: 10.1101/269415)

The authors describe a copy-move detection algorithm that finds reused images in the biological sciences literature even if they have been rotated, resized or had their contrast or colours changed. An analysis of figure element reuse is presented on a large dataset comprising 760,000 open access articles and 2 million figures.
