A 640×480 placeholder image with its dimensions labelled on a coloured grid — a drop-in stand-in for testing layouts, responsive images, and thumbnail generation. Part of an avatar-to-Full-HD placeholder pack.
A 800×600 placeholder image with its dimensions labelled on a coloured grid — a drop-in stand-in for testing layouts, responsive images, and thumbnail generation. Part of an avatar-to-Full-HD placeholder pack.
The pixel-identical PNG control with text and ICC chunks removed, for proving that a scrubber changes metadata without changing decoded RGB values.
A deterministic PNG with known text chunks and an embedded sRGB ICC profile, paired with a pixel-identical stripped control for extraction and privacy-tool tests.
The binary ground-truth mask for the portrait subject (white = foreground) — the reference for scoring a portrait cut-out or background blur.
A cat 'portrait' on a busy background — a portrait-style subject-detection and matting input, paired with its ground-truth mask.
A potted plant with many thin leaves and stems on transparency — the canonical fine-edge test for how cleanly a background remover cuts around delicate foliage.
A 256×256 fruit still-life image as binary Netpbm P6 (24-bit colour) — the minimal, header-plus-raw-pixels family used across Unix imaging tools. For testing Netpbm parsers and conversion.
The same photo as a progressive JPEG (loads coarse-to-fine) — the twin of the baseline JPEG, for testing progressive decoding and byte-order handling.

Clean reference for the dust photo-restoration case. Diff a restorer's output against this file; the damaged input and mask share group img-restore-dust.
Clean reference for the horizontal-cut photo-restoration case. Diff a restorer's output against this file; the damaged input and mask share group img-restore-horizontal-cut.
Clean reference for the scratch photo-restoration case. Diff a restorer's output against this file; the damaged input and mask share group img-restore-scratch.
Clean reference for the torn-corner photo-restoration case. Diff a restorer's output against this file; the damaged input and mask share group img-restore-torn-corner.
Clean reference for the water-stain photo-restoration case. Diff a restorer's output against this file; the damaged input and mask share group img-restore-water-stain.
