Inputs (35)
| Name | Type | Default | Description |
|---|---|---|---|
| images | IMAGE | — | |
| method | COMBO | birefnet-general | Background removal method. BiRefNet models are state-of-the-art and working great with FP16! |
| guidance_maskopt | MASK | — | |
| depth_mapopt | IMAGE | — | |
| reference_backgroundopt | IMAGE | — | |
| processing_resolutionopt | INT | 1024256–4096 | Processing resolution. Higher = better quality but slower. |
| use_gpuopt | BOOLEAN | true | Use GPU acceleration. Highly recommended for AI methods. |
| model_precisionopt | COMBO | fp16 | FP16 uses 50% less memory and is 2x faster with great quality! |
| use_guidance_maskopt | BOOLEAN | true | Use guidance mask if provided. White areas = keep, black areas = remove. |
| guidance_mask_strengthopt | FLOAT | 0.700–1 | Strength of guidance mask influence. |
| use_depth_guidanceopt | BOOLEAN | true | Use depth map if provided. Closer objects (brighter) = foreground. |
| depth_thresholdopt | FLOAT | 0.500–1 | Depth threshold. Objects closer than this are considered foreground. |
| depth_falloffopt | FLOAT | 0.200.05–0.5 | Smooth transition distance around depth threshold. |
| combine_depth_with_aiopt | BOOLEAN | true | Combine depth guidance with AI predictions for best results. |
| chroma_coloropt | COMBO | green | Chroma key background color. Green is most common for LED walls. |
| primary_thresholdopt | FLOAT | 0.120.01–0.5 | Primary color tolerance. Lower = more precise. 0.12 optimal for LED walls. |
| secondary_thresholdopt | FLOAT | 0.030.01–0.3 | Secondary refinement for edges. Lower = cleaner edges. |
| saturation_thresholdopt | FLOAT | 0.400.1–1 | Minimum saturation. 0.4 optimal for modern LED screens. |
| brightness_minopt | FLOAT | 0.150–1 | Minimum brightness for chroma key detection. |
| brightness_maxopt | FLOAT | 0.950–1 | Maximum brightness for chroma key detection. |
| multi_pass_keyingopt | BOOLEAN | true | Multi-stage processing for professional edge quality. |
| spill_suppressionopt | FLOAT | 0.850–1 | Remove color bleeding on subject edges. 0.85 optimal for most scenarios. |
| spill_preserve_luminanceopt | BOOLEAN | true | Preserve brightness during spill removal for natural results. |
| edge_softnessopt | FLOAT | 1.500–10 | Edge blur for smooth transitions. 1.5 optimal for most images. |
| core_matte_chokeopt | FLOAT | 0.00-0.5–0.5 | Expand (negative) or contract (positive) the matte core. |
| luma_key_modeopt | COMBO | shadows_highlights | Luma key removal mode. |
| shadow_thresholdopt | FLOAT | 0.080–0.5 | Shadow removal threshold. Lower = more shadows removed. |
| highlight_thresholdopt | FLOAT | 0.920.5–1 | Highlight removal threshold. Higher = more highlights removed. |
| luma_softnessopt | FLOAT | 0.050–0.5 | Luma key soft transition distance. |
| difference_thresholdopt | FLOAT | 0.080.01–0.5 | Difference key sensitivity. Lower = more sensitive. |
| color_space_modeopt | COMBO | hsv | Color space for processing. HSV recommended for chroma key, LAB for quality. |
| garbage_matte_enabledopt | BOOLEAN | false | Automatically remove obvious background areas. |
| remove_small_objectsopt | BOOLEAN | true | Remove small noise objects from mask. |
| small_object_thresholdopt | INT | 30050–2000 | Size threshold for small object removal (pixels). |
| mask_bluropt | FLOAT | 0.80–5 | Final mask blur for smoother edges. |
