ComfyUI Node: NoiseInjectionHookProvider

NoiseInjectionHookProvider:

The NoiseInjectionHookProvider is a specialized node designed to inject noise into your AI-generated images, enhancing their texture and detail. This node is particularly useful for AI artists looking to add a layer of controlled randomness to their creations, making them appear more natural and less uniform. By leveraging different noise schedules and sources, this node allows you to fine-tune the noise characteristics, ensuring that the final output meets your artistic vision. The primary function of this node is to create a noise injection hook that can be used during the upscaling process, adding a unique touch to your images.

NoiseInjectionHookProvider Input Parameters:

schedule_for_iteration

This parameter determines the noise injection schedule to be used during the iteration process. The available option is "simple". This schedule defines how the noise will be applied over the iterations, impacting the final texture and detail of the image.

source

This parameter specifies the computational source for generating the noise. You can choose between "CPU" and "GPU". Selecting "GPU" can speed up the process if you have a compatible graphics card, while "CPU" is a more universally available option.

seed

This integer parameter sets the seed for the noise generation, ensuring reproducibility. The default value is 0, with a minimum of 0 and a maximum of 0xffffffffffffffff. Changing the seed will result in different noise patterns, allowing for a variety of textures.

start_strength

This float parameter defines the initial strength of the noise at the beginning of the iteration process. The default value is 1.0, with a range from 0.0 to 200.0 and a step size of 0.01. Higher values will result in more pronounced noise at the start.

end_strength

This float parameter sets the final strength of the noise at the end of the iteration process. Like start_strength, it has a default value of 1.0, with a range from 0.0 to 200.0 and a step size of 0.01. Adjusting this value will control how the noise intensity changes over the iterations.

NoiseInjectionHookProvider Output Parameters:

PK_HOOK

The output of this node is a PK_HOOK, which is a noise injection hook that can be used in subsequent processing steps. This hook encapsulates all the noise parameters and schedules, making it easy to apply consistent noise effects across different stages of your workflow.

NoiseInjectionHookProvider Usage Tips:

• Experiment with different seed values to generate a variety of noise patterns and textures in your images.
• Use the start_strength and end_strength parameters to control the intensity of the noise over the iteration process, creating dynamic and evolving textures.
• If you have a compatible GPU, select "GPU" as the source to speed up the noise generation process.

NoiseInjectionHookProvider Common Errors and Solutions:

[ERROR] NoiseInjectionHookProvider: 'ComfyUI Noise' custom node isn't installed. You must install 'BlenderNeko/ComfyUI Noise' extension to use this node.

• Explanation: This error occurs when the required 'ComfyUI Noise' extension is not installed.
• Solution: Install the 'BlenderNeko/ComfyUI Noise' extension from the provided URL to resolve this issue.

Exception: 'BNK_NoisyLatentImage', 'BNK_InjectNoise' nodes are not installed.

• Explanation: This error indicates that the necessary nodes for noise injection are missing.
• Solution: Ensure that the 'BNK_NoisyLatentImage' and 'BNK_InjectNoise' nodes are installed correctly. You may need to reinstall the 'ComfyUI Noise' extension.
