Denoise Base A — Clean Reference (512px)
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.
Test images for denoise filters
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.
Gaussian Noise σ=10 — Base A (512px)
Base A with additive Gaussian noise at σ=10 (seed 4210). Compare against the clean reference in this set to score a denoise filter.
Gaussian Noise σ=25 — Base A (512px)
Base A with additive Gaussian noise at σ=25 (seed 4225). Compare against the clean reference in this set to score a denoise filter.
Gaussian Noise σ=50 — Base A (512px)
Base A with additive Gaussian noise at σ=50 (seed 4250). Compare against the clean reference in this set to score a denoise filter.
Salt & Pepper 2% — Base A (512px)
Base A with 2% salt-and-pepper noise (seed 42002). A direct fixture for testing median and morphological denoisers against the clean reference.
Salt & Pepper 5% — Base A (512px)
Base A with 5% salt-and-pepper noise (seed 42005). A direct fixture for testing median and morphological denoisers against the clean reference.
Salt & Pepper 10% — Base A (512px)
Base A with 10% salt-and-pepper noise (seed 42010). A direct fixture for testing median and morphological denoisers against the clean reference.
