ComfyUI Node: Fake Scribble Lines (aka scribble_hed)

Fake Scribble Lines (aka scribble_hed):

The FakeScribblePreprocessor is designed to generate scribble-like line art from images, leveraging the HED (Holistically-Nested Edge Detection) model. This node is particularly useful for AI artists who want to create stylized, sketch-like representations of their images. By converting images into scribble lines, it provides a unique and artistic way to preprocess images for further creative applications. The node ensures that the generated lines are soft-edged and can be adjusted for safety, making it versatile for various artistic needs.

Fake Scribble Lines (aka scribble_hed) Input Parameters:

safe

The safe parameter determines whether the safety mode is enabled or disabled. When set to "enable," the node applies additional processing to ensure the output is safe and free from artifacts that might arise during the edge detection process. This can be particularly useful when working with images that have complex textures or details. The default value is "enable," and the available options are "enable" and "disable."

resolution

The resolution parameter specifies the resolution at which the image will be processed. A higher resolution can result in more detailed and accurate scribble lines, but it may also increase the processing time. The default value is 512, and it can be adjusted according to the desired level of detail and the performance capabilities of your system.

Fake Scribble Lines (aka scribble_hed) Output Parameters:

IMAGE

The output parameter IMAGE represents the processed image with scribble-like lines. This output is a stylized version of the input image, where the edges and contours are highlighted in a sketch-like manner. The resulting image can be used as a base for further artistic manipulation or as a final piece of artwork.

Fake Scribble Lines (aka scribble_hed) Usage Tips:

• To achieve the best results, start with the default resolution of 512 and adjust based on the complexity of your image and the level of detail you desire.
• Enable the safe mode to avoid any unwanted artifacts, especially when working with images that have intricate details or textures.
• Experiment with different input images to see how the scribble lines vary and find the style that best suits your artistic vision.

Fake Scribble Lines (aka scribble_hed) Common Errors and Solutions:

"Model loading failed"

• Explanation: This error occurs when the HED model fails to load, possibly due to missing files or incorrect paths.
• Solution: Ensure that the HED model files are correctly installed and accessible. Verify the file paths and reinstall the model if necessary.

"Invalid resolution value"

• Explanation: This error is triggered when the resolution parameter is set to a value outside the acceptable range.
• Solution: Check the resolution value and ensure it is within the supported range. The default value is 512, and it should be adjusted according to the node's specifications.

"Safe mode parameter missing"

• Explanation: This error occurs when the safe parameter is not provided or is incorrectly specified.
• Solution: Ensure that the safe parameter is included in the input and set to either "enable" or "disable." The default value is "enable."
