# Documentation
- Class name: SaltMaskFloorRegion
- Category: SALT/Masking/Filter
- Output node: False

SaltMaskFloorRegion节点旨在识别和提取给定掩码中的地板区域。它会处理每个掩码以提取地板区域，并将其转换为表示地板区域的张量。

# Input types
## Required
- masks
    - 需要识别地板区域的输入掩码。这些掩码将被处理以提取地板区域，对节点的输出有重大影响。
    - Comfy dtype: MASK
    - Python dtype: torch.Tensor

# Output types
- MASKS
    - 表示输入掩码中被隔离的地板区域的输出张量。
    - Comfy dtype: MASK
    - Python dtype: torch.Tensor


## Usage tips
- Infra type: `GPU`
- Common nodes: unknown

            region_mask = MaskFilters.floor_region(pil_image)
            region_tensor = pil2mask(region_mask)
            regions.append(region_tensor)
        regions_tensor = torch.cat(regions, dim=0)
