Images with full data (PSNR table + filtered images + varying number of manifolds)

Click on any image to open a PSNR comparison page. The mean PSNR value shown in the caption of any given image corresponds to the average of the PSNR values obtained when filtering that image with adaptive-manifold filters using the 64 combinations of σ_s and σ_r values shown on the table at the bottom of this page. Please see our project website for more images with full data.

Images with PSNR table only

Mean PSNR table for all 24 test images

Average of the PSNR value among all images for a given combination of σ_s and σ_r values.
