Coffee Mug on Studio Background (512px)
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 test images
Product-on-background compositions, alpha PNGs over transparency, and fine-edge tests for background removers.
Coffee Mug — Transparent Cut-out (512px)
The expected transparent cut-out of the coffee mug, paired with the on-background version — the ground truth for a background-removal test.
Coffee Mug with Soft Shadow (512px)
The coffee mug with a soft drop shadow on transparency — tests whether a background remover keeps or discards the contact shadow.
Semi-Transparent Drinking Glass (512px)
A half-full drinking glass rendered with partial transparency — the hard case for background removers that assume every subject pixel is opaque.
Alpha-Channel Reveal (512px)
A left-to-right alpha gradient over a solid colour, for testing how a viewer or compositor renders partial transparency.
Potted Plant — Fine-Edge Test (512px)
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.
Apple on Cluttered Background (512px)
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.
Apple — Ground-Truth Cut-out (512px)
The ground-truth transparent cut-out of the apple used in the cluttered-background hard case — the ideal output of a perfect background remover.
Apple — Ground-Truth Alpha Mask (512px)
The binary ground-truth alpha mask (white = subject, black = background) for the cluttered-background apple — compute IoU or boundary F-score of a predicted mask against this file.
