bg-remover

<objective> Remove the background from a photo. Single input image → output PNG with transparent (alpha channel) background. Subject preserved as-is; everything else becomes transparent. This skill does NOT: - Replace the background with a new image — for that, use the transparent PNG output + paste into a new background in your image editor, OR use `image-prompt --execute --model flux-kontext --image-url <photo> --prompt "subject in new setting"` for full reimagining - Remove specific objects from a complex scene — only removes BACKGROUND (everything not the main subject) - Process video — single image only (per call) - Restore / upscale / sharpen — see future `upscaler` skill </objective> ## ROLE Read the input image → call a Replicate-hosted bg-removal model → save the transparent PNG. ## PIPELINE 1. **Resolve input**: - `--image <path-or-url>` (required) - Local file or remote URL 2. **Pick provider**: - Default: `851-labs/background-remover` (popular, accurate on photos) - Alternatives via `--replicate-model <id>`: - `851-labs/background-remover` — default; best general - `lucataco/remove-bg` — alternative - `cjwbw/rembg` — Python `rembg` library hosted - `pollinations/modnet` — MODNet (good for portraits) - Other Replicate bg-removers: pass via `--replicate-model <slug>` 3. **Execute** via the Replicate router (REPLICATE_API_TOKEN required). 4. **Save**: - Default: `./generated/bg-removed/<input-stem>-nobg.png` (transparent)...
