Noisy images paired with their exact clean reference, with documented noise type, sigma, and seed — everything you need to measure how well a denoise filter recovers the original.
The clean reference image for denoise base A — a fruit still life on studio white. Diff the noisy variants in this set against this file to measure filter accuracy.
Base A with additive Gaussian noise at σ=10 (seed 4210). Compare against the clean reference in this set to score a denoise filter.
Base A with additive Gaussian noise at σ=25 (seed 4225). Compare against the clean reference in this set to score a denoise filter.
Base A with additive Gaussian noise at σ=50 (seed 4250). Compare against the clean reference in this set to score a denoise filter.
Base A with 2% salt-and-pepper noise (seed 42002). A direct fixture for testing median and morphological denoisers against the clean reference.
Base A with 5% salt-and-pepper noise (seed 42005). A direct fixture for testing median and morphological denoisers against the clean reference.
Base A with 10% salt-and-pepper noise (seed 42010). A direct fixture for testing median and morphological denoisers against the clean reference.
The clean reference image for denoise base B — a coffee mug on studio white. Diff the noisy variants in this set against this file to measure filter accuracy.
