Hi, Gili. Interesting topic. Leon Harmon's well-known work on facial recognition in which he produced the pixelated images of Washington and Lincoln wasn't about censoring, of course, but it's implicit that extreme transformations would prevent recognition. The Recognition of Faces. Scientific American (1973 Nov) 229(5):71-82. - Bill ________________________________ From: Members [members-bounces@lists.sigcis.org] on behalf of Gili Vidan [gvidan@g.harvard.edu] Sent: Wednesday, November 15, 2017 7:16 PM To: members@lists.sigcis.org Subject: [SIGCIS-Members] Sources/Lit on history of pixelization Hello SIGCIS, I’m wondering if anyone knows about scholarship on the history of pixelization as a technique for partially censoring visual content? I am advising an undergraduate student who’d like to write about the subject and not sure where to direct her efforts. Thanks! Gili Vidan
