Everything about Standard Test Image totally explained
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.
Kodak test set for compression comparisons
Kodak has released a set of 24 losslessly compressed 768×512 images, available as
PNGs, that are widely used for comparing image compression techniques.
Common test images
The standard size of the images are usually 512x512 or 720x576. Most of these images are freely available as
TIFF files from the
University of Southern California's Signal and Image Processing Institute.
