In addition to lenna old timer image processing researchers would also have fond (depending whether your compression or edge detection algorithm worked correctly or not) memories of girl, cameraman, and barbara images as well as the infamous baboon (https://goo.gl/images/4Js7YH https://goo.gl/images/4Js7YH).
