| Fixture findings | Clean subject silhouette (99.87% foreground recall, 0.015% background leak) with moderate smoothing along fine peripheral hair strands and a boundary MAD of 0.0886 (53.5/65). | Preserves full 2048×2048 resolution and main subject silhouette; semi-transparent halo remains in curly hair gaps. |
| Original historical observation | High foreground recall (99.87%) and near-zero background leakage (0.015%), with slight resolution loss from the 2000×2000 free-tier input resize and moderate smoothing on fine peripheral hair wisps. | Against green and black backdrops, the 2048×2048 cutout preserves the full portrait and outer curl silhouette without cropping, though semi-transparent background residue remains along fine curly flyaways. |
| Suitable uses · historical assessment | Users who already use the Nero AI suite and need clean unwatermarked cutouts up to 2000×2000px | Users who need a genuinely free, no-login, full-resolution (2048×2048) unwatermarked transparent PNG cutout with optional solid-color or image background replacement |
