Start with the source
Look for similar colors, narrow gaps, reflections, soft edges, and where the subject touches the ground.
Results, not a score
Background removal quality test: inspect the pixels yourself.
14 source images were run through the current Stable Diffusion AI background-removal product. Each case shows the untouched source, the actual transparent PNG, and that same PNG over white and dark surfaces.

How to read this test
A good cutout survives the destination surface.
Open the PNG
Checkerboard exposes transparency, but it can hide pale halos and dark edge contamination.
Change the surface
White and dark previews reveal edge spill without changing the actual result pixels.
CASE 01
Curly hair portrait
Dense curls and small exterior loops against a natural background.
- Inspect: Outer curl continuity
- Inspect: Background color trapped between curls
- Inspect: Face, shoulder, and clothing boundaries
CASE 02
Reflective product bottle
A glossy blue bottle with highlights and a hard product silhouette.
- Inspect: Cap and shoulder silhouette
- Inspect: Reflection preservation
- Inspect: Halo or color spill along both sides
CASE 03
Pet fur in a garden
Fine fur against a detailed outdoor background.
- Inspect: Fine fur around ears and body
- Inspect: Green spill from foliage
- Inspect: Ground contact and paws
CASE 04
Object with thin radial details
A wooden sunburst object with narrow rays and interior gaps.
- Inspect: Thin ray continuity
- Inspect: Transparency inside narrow gaps
- Inspect: False background fragments near the center
CASE 05
Raster logo with internal holes
A fictional fine-line botanical mark on opaque cream paper, with narrow branches, counters, and overlapping enclosed shapes.
- Inspect: Continuity of narrow branches
- Inspect: Transparency inside leaf and flower counters
- Inspect: Cream matte fringe on light and dark surfaces
CASE 06
Reflective car in a dealership lot
A metallic SUV with mirrors, roof rails, wheel gaps, glass, reflections, and ground contact against a busy lot.
- Inspect: Mirror, roof-rail, and antenna silhouette
- Inspect: Wheel gaps and tire contact edges
- Inspect: Lot residue in glass reflections and pale halo on bodywork
CASE 07
Clear glass and water
A clear pitcher and tumbler whose photographed background remains visible through transparent material and water.
- Inspect: Handle and rim continuity
- Inspect: Old-scene detail retained inside glass and water
- Inspect: Bright fringe around transparent edges
CASE 08
Bicycle spokes and cables
Thin spokes, brake cables, drivetrain gaps, and two large open wheel interiors against foliage.
- Inspect: Spoke and cable continuity
- Inspect: Green or yellow residue inside wheel gaps
- Inspect: Fine drivetrain detail near the rear hub
CASE 09
Chair with narrow spindle gaps
A wooden chair with many repeated openings, curved rails, and floor-contact legs.
- Inspect: Transparency between every spindle
- Inspect: Interior edge residue along dark gaps
- Inspect: Complete feet and support rails
CASE 010
Plant with overlapping leaves
Hundreds of narrow leaves and branches create dense exterior detail and many small interior gaps.
- Inspect: Leaf-tip continuity
- Inspect: Small holes inside dense foliage
- Inspect: Pale or green fringe around branches
CASE 011
Jewelry chain and open hoops
A fine necklace chain, clasp, small stones, and circular earrings on a textured surface.
- Inspect: Continuity of the finest chain links
- Inspect: Open earring interiors
- Inspect: Missing or merged pixels around small stones and clasps
CASE 012
Product with a real soft shadow
A ceramic lamp with a fabric shade, power cord, tabletop contact, and a soft photographed cast shadow.
- Inspect: Fabric shade edge and ceramic silhouette
- Inspect: Whether the thin power cord survives
- Inspect: Loss of the photographed soft shadow and contact context
CASE 013
Straight hair and loose wisps
Long dark hair with narrow gaps, isolated strands, and similar dark tones in the original scene.
- Inspect: Single-strand continuity near cheeks and shoulders
- Inspect: Dark-scene contamination in hair gaps
- Inspect: Shoulder and sweater boundary
CASE 014
Backlit flyaway hair
Warm backlight makes dozens of translucent flyaways and curls brighter than the busy park behind them.
- Inspect: Outer flyaway continuity
- Inspect: Warm rim-light fringe on dark and white surfaces
- Inspect: Small transparent gaps between curls
Coverage boundary
What this page does not prove
These 14 cases do not establish quality for every image. In particular, the current published set does not yet include:
- smoke, mist, veils, and other semi-transparent fabric
- transparent retail packaging with printed labels
- wire fencing, mesh, and netting
- heavy subject or camera motion blur
- subjects whose color closely matches the background
- sources where the subject is already cropped by the frame
No aggregate score is published because this project-owned sample set is not representative of every source distribution, and there is no hand-labeled ground-truth mask for a defensible accuracy metric.
Recovery path
When your edge is not usable
- 1. Check both light and dark. A light halo can disappear on white and remain obvious elsewhere.
- 2. Use Refine cutout. Erase leftover background or restore removed subject pixels with undo and redo.
- 3. Keep the original Creation. A refinement is saved as a derivative, so the automatic result stays available for another attempt.
- 4. Use the task-specific output. Product and white-background tools let you control fit, position, padding, canvas, and format after removal.
How results stay comparable
The source files never change. When the live remover changes, every source is processed again and published as a new version. Transparency and dimensions are checked first, then every cutout is reviewed on checkerboard, white, and dark surfaces. Earlier results remain available instead of being silently replaced.
