Lena-image Memes

The history of digital image processing is... interesting. Back in the early days, computer scientists needed test images to develop algorithms for compression, filtering, and analysis. Problem was, they needed something standardized everyone could use. Enter the November 1972 issue of Playboy. Some researchers at USC literally scanned a centerfold (Miss November, Lena Forsén) and it became THE standard test image in computer vision for decades. Every image processing textbook, every research paper, every university lecture - there's Lena. So yeah, you'd be sitting in your serious academic Computer Vision class, professor droning on about convolution kernels and edge detection, and BAM - cropped Playboy centerfold on the projector. Nobody talks about it, everyone just accepts it. Peak academic awkwardness meets "we've always done it this way" energy. The image is still used today, though it's finally getting phased out because, you know, maybe using a Playboy model as the universal standard in a male-dominated field wasn't the best look.
