Images
Images are the most-tested files of all, yet generic sample sites hand you a photo with no documented properties. Here, every image records exactly what it is. Denoise, restoration, inpaint, deblur, upscale, colourization, watermark, outpaint, style-transfer, and enhance suites pair degraded inputs with clean references. Segmentation masks, visual-diff twins, EXIF/ICC ladders, multipage sprites, chart-vision, codec ladders, OCR hardcases, and soft-edge matting extend the set for modern vision QA. Clean ↔ noisy and colour ↔ greyscale pairs make before/after testing trivial.

Frequently asked questions
What makes these image fixtures different from random stock photos?+
Every image ships with documented specs (dimensions, seeds, damage type, pair/group IDs). Denoise, restoration, colourization, watermark, and enhance suites include clean ground-truth twins so you can score tools with PSNR/SSIM instead of guessing.
Do you include real faces or brand watermarks?+
No. Face-restore fixtures use synthetic illustrations, and watermark suites use SAMPLE logos/text only. Corrupt samples are labelled intentionally corrupt.
How do I find before/after pairs?+
Open any suite member and use the Pair / Group links on the file page, or filter Browse by purpose (for example colourization-testing or watermark-removal-testing).
What vision / QA suites landed in the latest expansion?+
Wave E adds segmentation scene/mask/JSON triples, A/B diff-regression twins, EXIF Orientation + ICC colour notes, multipage TIFF / sprite / favicon packs, chart-as-image mocks, codec quality ladders, hard OCR cases, and soft-alpha matting hardcases.
