| Fixture findings | Relatively clean translucent hair edges; the 2048px input became a 1673px output in this test. | Local processing with full-size output; complex curly-hair edges look blocky and smoothed. |
| Original historical observation | VanceAI BGremover segments frizzy curly hair transitions cleanly (mad_band=0.0950, bg_leak=0.222%) with zero visible color fringing across green, black, and white backdrops; its only limitation is normalizing 2048px input to 1673×1673. | 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. |
| Suitable uses · historical assessment | Users who want high-precision no-login hair cutouts (1673×1673 unwatermarked) and seamless chaining with 4x upscaling or sharpening in one workspace | Privacy-sensitive users who require 0-byte cloud upload (100% local browser execution) and unlimited no-login 2048×2048 full-resolution exports |
