OpenDenoising: an Extensible Benchmark for Building Comparative Studies of Image Denoisers [article]

Florian Lemarchand, Eduardo Fernandes Montesuma, Maxime Pelcat, Erwan Nogues
2019 arXiv   pre-print
Image denoising has recently taken a leap forward due to machine learning.  ...  However, image denoisers, both expert-based and learning-based, are mostly tested on well-behaved generated noises (usually Gaussian) rather than on real-life noises, making performance comparisons difficult  ...  These methods are evaluated on well-behaved noises (typically AWGN) for the tests to be easily reproducible. Only Noise2Void is evaluated on medical images subject to complex noise.  ...
