| Fixture findings | Fine curls were well retained with semi-transparency enabled; the result is specific to this mode and fixture. | Complete subject contours with little residue; this free export was only 500px and blurred fine hair. |
| Original historical observation | With Semi-transparency enabled, Leonardo.Ai's Remove Background preserves fine outer curls exceptionally well—achieving 99.87% foreground recall, SAD(k)=25.541, and mad_band=0.164 at full 2048×2048 resolution. | High foreground recall (99.81%) and low background leak (0.038%); transition band error mad_band=0.1036, SAD(k)=40.93, with mild edge softening when upsampled from the 500×500 free preview. |
| Suitable uses · historical assessment | Creators needing ultra-high curly hair recall (99.87%) and direct integration with Canva Magic Layers or AI generation workflows | Users familiar with remove.bg's workflow needing quick guest 500px previews or desktop/Photoshop integrations |
