Input fields for birefnet
Name	Type	Description
`model`	string (enum)	Model to use for background removal. The 'General Use (Light)' model is the original model used in the BiRefNet repository. The 'General Use (Heavy)' model is a slower but more accurate model. The 'Portrait' model is a model trained specifically for portrait images. The 'General Use (Light)' model is recommended for most use cases. The corresponding models are as follows: - 'General Use (Light)': BiRefNet-DIS_ep580.pth - 'General Use (Heavy)': BiRefNet-massive-epoch_240.pth - 'Portrait': BiRefNet-portrait-TR_P3M_10k-epoch_120.pth Default: `General Use (Light)` One of: `General Use (Light)`, `General Use (Heavy)`, `Portrait`
`operating_resolution`	string (enum)	The resolution to operate on. The higher the resolution, the more accurate the output will be for high res input images. Default: `1024x1024` One of: `1024x1024`, `2048x2048`
`output_mask`	boolean	Whether to output the mask used to remove the background Default: `false`
`refine_foreground`	boolean	Whether to refine the foreground using the estimated mask Default: `true`
