This is the story of how a single image defined the engineering constraints of the early internet and continues to haunt the ethics of dataset curation. At the University of Southern California’s Signal and Image Processing Institute (SIPI), assistant professor Alexander Sawchuk needed a high-contrast, high-detail image to scan for a colleague’s conference paper. The lab’s flatbed scanner (one of the first) was crude: 100 lines per inch, 6 bits per pixel.
"Using a soft-core porn image as the default test for serious engineering normalizes the exclusion of women. It signals that the lab is a frat house, not a professional environment." webmodels lena
But the web is growing up. New models are trained on diverse, consented, curated datasets. Lena has been retired to the museum of computing—a beautiful, problematic, and utterly foundational piece of engineering history. This is the story of how a single
