Documentation

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

此节点旨在利用专门在ADE20K数据集上训练的OneFormer模型进行语义分割任务。它预处理图像以促进语义分割，利用预训练的OneFormer模型根据ADE20K数据集标准分析并将输入图像分割成不同的语义类别。

Input types

Required

• image
  • 待进行语义分割的输入图像。该图像将使用OneFormer模型进行处理并分割成不同的语义类别。
  • Comfy dtype: IMAGE
  • Python dtype: torch.Tensor

Optional

• resolution
  • 指定分割后输出图像的分辨率。这会影响分割输出的细节水平和尺寸。
  • Comfy dtype: INT
  • Python dtype: int

Output types

• image
  • 语义分割过程的输出，是一张被分割成不同语义类别的图像。
  • Comfy dtype: IMAGE
  • Python dtype: torch.Tensor

Usage tips

• Infra type: GPU
• Common nodes: unknown
