| Fixture findings | Local processing with full-size output; complex curly-hair edges look blocky and smoothed. | Preserves full 2048×2048 resolution and main subject silhouette; semi-transparent halo remains in curly hair gaps. |
| Original historical observation | Constrained by lightweight client-side WebGL/WASM model capacity, complex curly hair outer edges show softer semi-transparent halos (mad_band=0.1481, SAD(k)=65.96) compared to heavy cloud models, but foreground recall reaches 99.38% at full 2048×2048 resolution. | 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 | Privacy-sensitive users who require 0-byte cloud upload (100% local browser execution) and unlimited no-login 2048×2048 full-resolution exports | Users who need a genuinely free, no-login, full-resolution (2048×2048) unwatermarked transparent PNG cutout with optional solid-color or image background replacement |
