Remove Background (Two-Pass)

Runs background removal twice for cleaner edges and smoother alpha blending. The second pass often removes artifacts the first pass left behind.

When to use

• Single-pass result has visible halos or stray pixels around fine details (hair, fur, thin branches)
• Default single-pass is too aggressive or too conservative on edge preservation

Inputs to gather

• Image path — same JPEG/PNG/WebP/BMP/TIFF file to process again (typically the original, or feed the -nobg.png from a previous run)
