Standard test image

From Wikipedia, the free encyclopedia

A standard test image is a digital image file used across different institutions to test image processing and image compression algorithms. By using the same standard test images, different labs are able to compare results, both visually and quantitatively. The images are in many cases chosen to represent natural or typical images that a class of processing techniques would need to deal with. Other test images are chosen because they present a range of challenges to image reconstruction algorithms, such as the reproduction of fine detail and textures, sharp transitions and edges, and uniform regions.

The most widely published standard test image is the Lenna image, from a 1972 centerfold photograph of Playboy model Lena Soderberg.
