| Fixture findings | Delivers 99.84% foreground recall and 0.02% background leak at 2048x2048, with natural boundary transitions, authentic Alpha channel, and zero watermarks. | Fine curls were well retained with low edge error in this test; other subjects are not established by this result. |
| Original historical observation | SeaArt demonstrated top-tier precision on anchor_bgremove_v1, preserving delicate curly hair strands (99.84% recall) with near-zero background residue (0.02% leak) at 2048x2048. | Underlying segmentation model is outstanding (mad_band=0.0748, SAD(k)=27.9, #2 in raw hair edge accuracy), which makes its aggressive cross-product redirect dark pattern all the more unfortunate. |
