Documentation

  • Class name: OneFormer-ADE20K-SemSegPreprocessor
  • Category: ControlNet Preprocessors/Semantic Segmentation
  • Output node: False

OneFormer ADE20K Segmentor节点专门用于语义分割任务,它使用在ADE20K数据集上预训练的OneFormer模型。该节点处理输入图像,对其进行语义分割,即根据ADE20K数据集的预定义类别,识别并分类图像中的每个像素。

Input types

Required

  • image
    • 需要进行语义分割的输入图像。该图像将由OneFormer模型处理,以识别和分类每个像素。
    • Comfy dtype: IMAGE
    • Python dtype: torch.Tensor

Optional

  • resolution
    • 在处理前将输入图像调整到的分辨率。这会影响分割输出的细节水平。
    • Comfy dtype: INT
    • Python dtype: int

Output types

  • image
    • 语义分割过程的输出。这是一张图像,其中每个像素根据ADE20K数据集被分类到特定类别。
    • Comfy dtype: IMAGE
    • Python dtype: torch.Tensor

Usage tips

  • Infra type: GPU
  • Common nodes: unknown
