Product-on-background compositions, alpha PNGs over transparency, and hard-case edges (fur, mesh, glass refraction, colour-matched backgrounds) for scoring removers and recomposite workflows.
Each card starts with one representative test file. Choose a use case, search, or filter to find a specific profile; a card’s variant menu contains its related samples.

Background Removal
A left-to-right alpha gradient over a solid colour, for testing how a viewer or compositor renders partial transparency.
Background Removal
An apple on a busy, colour-matched background: the hard input for a background remover or matting model. Score a prediction against the paired ground-truth cut-out and alpha mask.
Background Removal
A coffee mug photographed on a clean studio-white background: the easy input for a background remover, paired 1:1 with its transparent cut-out for scoring.
Background Removal
The coffee mug with a soft drop shadow on transparency. Tests whether a background remover keeps or discards the contact shadow.
Background Removal
Subject colours deliberately match the background clutter: a hard segmentation case.
Background Removal
Synthetic fur-like fibres on a cluttered background: a classic background-removal failure case.
Background Removal
Semi-transparent glass bottle on clutter, partial-alpha background-removal hard case.
Background Removal
Mug with a handle interior hole on clutter: background should show through the handle.
Background Removal
Chain-link / mesh with interior holes. Tests whether a removers keeps background visible through the grid.
Background Removal
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.
Background Removal
A half-full drinking glass rendered with partial transparency: the hard case for background removers that assume every subject pixel is opaque.
