The Lenna image used in image processing tests is considered problematic due to its unclear copyright status. Right now it is considered to be "overlooked" by the copyright holder Playboy. A suitable replacement image is already provided in the libav sources which is licensed under the Expat (MIT) license and thus truly free. This replaces the Lenna image with the one from the libav project.
