So funny story worth the read. If you were to start down a road of image processing, doing things like creating photoshop filters, doing image analysis, restoration, repair, deblur.... I mean there are a billion different image processing applications. Anyways, when you are learning the techniques you need sample pictures to work on. And by an overwhelming margin almost all Signal processing books/classes use an image called lena.png as the test image.
In July of 1973 when Alexander Sawchuk, then an assistant professor of electrical engineering at the USC Signal and Image Processing Institute (SIPI), along with a graduate student and the SIPI lab manager, was hurriedly searching the lab for a good image to scan for a colleague's conference paper. They had tired of their stock of usual test images, dull stuff dating back to television standards work in the early 1960s. They wanted something glossy to ensure good output dynamic range, and they wanted a human face. This is what they ended up presenting at the conference:
Apparently this caused quite a bit of controversy as this image was copyrighted. They were sued by the copy right holders. And people in the image processing field have debated about not using it due to where it came from.... However 40 years later is is still the most highly used image in image processing. you can't take a class without knowing Lena.
