- Class name: OneFormer-COCO-SemSegPreprocessor
- Category: ControlNet Preprocessors/Semantic Segmentation
- Output node: False
OneFormer COCO Segmentor节点使用经过COCO数据集训练的预训练OneFormer模型对图像进行语义分割。它旨在识别和描绘图像中的每个语义对象,从而在像素级别上增强对图像内容的理解。
Input types
Required
- image
- 需要进行语义分割的输入图像。这个参数至关重要,因为它直接影响分割输出,决定了图像中的对象及其边界。
- Comfy dtype: IMAGE
- Python dtype: torch.Tensor
Optional
- resolution
- 指定在进行分割之前将输入图像调整到的分辨率。这个参数影响分割输出的细节水平,较高的分辨率可能会导致更精确的分割结果。
- Comfy dtype: INT
- Python dtype: int
Output types
- image
- 语义分割过程的输出,表现为一幅图像,其中每个像素的值对应一个语义类别。
- Comfy dtype: IMAGE
- Python dtype: torch.Tensor
