TEEDPreprocessor

Documentation

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

The TEEDPreprocessor node is designed for preprocessing images to extract soft-edge lines using the TEED (TEDDetector) model. It enhances the input image by applying a specialized line extraction technique, making it suitable for further processing or analysis.

Input types

Required

• image
  • The input image to be processed for soft-edge line extraction.
  • Comfy dtype: IMAGE
  • Python dtype: torch.Tensor

Optional

• safe_steps
  • Defines the number of safe steps to take during the line extraction process, affecting the robustness and sensitivity of the detection.
  • Comfy dtype: INT
  • Python dtype: int
• resolution
  • Specifies the resolution at which the image should be processed, impacting the detail level of the extracted lines.
  • Comfy dtype: INT
  • Python dtype: int

Output types

• image
  • Comfy dtype: IMAGE
  • The output is an image that has undergone line extraction to highlight soft edges, making it more suitable for tasks requiring detailed line information.
  • Python dtype: torch.Tensor

Usage tips

• Infra type: GPU
• Common nodes: unknown
