Comparison to CBM3D

Surely CBM3D represents a state of the art image denoising. However, our algorithm exceeds the results of CBM3D for both real and hyperspectral images. Our stunning image restoration make our image denoising algorithm the best in the world. In the following charts, we use 5 color images downloaded from cbm3d website for comparison.

Hyperspectral Image Denoising

The keen accuracy of our image denoising algorithm specifically highlights the details of hyperspectral images. The radical difference of Peak Signal to Noise Ratio (PSNR) when using BM3D versus our algorithm is displayed below.

Compare Real Photo Results

For real world noisy photos, cbm3d just doesn't work since real word image noise is not simple gaussian noise and the noise level is unknown in advance. Moreover, the noise level is usually different for different colors. We extended our algorithm to handle real world noisy photos and compare it with a state of the art software Photo Ninja.
