Documentation

• Class name: LineartStandardPreprocessor
• Category: ControlNet Preprocessors/Line Extractors
• Output node: False

LineartStandardPreprocessor节点旨在使用标准方法从图像中提取线稿。它预处理图像以突出和细化线条细节，适用于需要清晰线条描绘的应用，如数字艺术和动画。

Input types

Required

• image
  • 需要进行线稿提取处理的输入图像。
  • Comfy dtype: IMAGE
  • Python dtype: Image

Optional

• guassian_sigma
  • 指定应用于图像的高斯模糊的sigma值，影响提取线条的平滑度。
  • Comfy dtype: FLOAT
  • Python dtype: float
• intensity_threshold
  • 决定强度差异的阈值，影响线稿与背景的区分。
  • Comfy dtype: INT
  • Python dtype: int
• resolution
  • 处理前将输入图像调整到的分辨率，影响提取线稿的细节级别。
  • Comfy dtype: INT
  • Python dtype: int

Output types

• image
  • 输出一张线条增强和细化后的图像，适合进一步处理或直接用于各种应用。
  • Comfy dtype: IMAGE
  • Python dtype: Image

Usage tips

• Infra type: CPU
• Common nodes: unknown
