Documentation

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

该节点是专门为使用OneFormer模型进行语义分割任务而设计的,特别是针对COCO数据集训练的模型。它预处理图像以便进行语义分割,利用预训练的OneFormer模型分析输入图像并将其分割成不同的语义类别。

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,以识别和分类图像中的不同语义元素。
    • Comfy dtype: IMAGE
    • Python dtype: torch.Tensor

Optional

  • resolution
    • resolution参数指定分割后图像的期望输出分辨率。它影响OneFormer模型执行语义分割的颗粒度和质量。
    • Comfy dtype: INT
    • Python dtype: int

Output types

  • image
    • 输出是一个语义分割后的图像,其中每个像素都被分类为COCO数据集定义的语义类别之一。
    • Comfy dtype: IMAGE
    • Python dtype: torch.Tensor

Usage tips

  • Infra type: GPU
  • Common nodes: unknown
