Demo Images and Free Software for "A
Universal Image Quality Index"
See the SSIM Index Page for an improved version
of the algorithm!!!

3: "Couple" image with different types of distortions
Demo
4: "Tiffany",
"Lake" and "Mandrill" images with JPEG compression
Demo
5: "Woman",
"Man" and "Barbara" images with blurring
An
efficient Matlab implementation of
the proposed universal image quality index algorithm is available here. You can
download it for free, change it as you like and use it anywhere, but please
refer to its original source (cite our paper and this web
page).
This
program takes about 2.4 seconds to calculate the quality of a 512 by 512 gray
scale image on my 1G Hz Pentium III computer. My more efficient C
implementation is more than 15 times faster than this Matlab program.
More insights related to this
method is described in another paper: Why
is image quality assessment so difficult?
