^ These algorithms have not been trained on the area averaging downscaling degradation[1], this has a negative effect on PSNR.
* These algorithms have not been trained on the Bicubic/Lanczos + Low pass filtering degradation, this has a negative effect on PSNR.

[1] The area averaging downscaling operation is the correct downscaling operation for all natural images and line art images. Bicubic interpolation and Lanczos introduces gradient overshoot when downscaling if used without a lowpass filter. Lowpass filtering adds blur to the image, which degrades fine detail present in line art.
