ComfyUI Node: LatentNoised

LatentNoised:

The LatentNoised node is designed to introduce noise into latent images, which are intermediate representations used in various AI models, particularly in generative tasks. This node allows you to manipulate the latent space by adding controlled noise, which can be useful for enhancing creativity, exploring variations, or testing the robustness of models. By adjusting the noise parameters, you can influence the randomness and structure of the generated outputs, making it a powerful tool for AI artists looking to experiment with different styles and effects. The node supports various noise types and configurations, providing flexibility in how noise is applied to the latent images.

LatentNoised Input Parameters:

add_noise

This parameter determines whether noise should be added to the latent image. If set to true, noise will be introduced based on the specified noise type and strength. This can significantly impact the final output by adding randomness and variation.

noise_is_latent

This parameter specifies if the noise should be treated as part of the latent space. When true, the noise is integrated into the latent image, potentially altering its characteristics and leading to different generative results.

noise_type

This parameter defines the type of noise to be applied. Different noise types can produce varying effects on the latent image, allowing for creative exploration and experimentation.

noise_seed

The noise seed is an integer value used to initialize the random number generator for noise creation. By setting a specific seed, you can ensure reproducibility of the noise pattern, which is useful for consistent results across different runs.

alpha

Alpha is a float parameter that influences the intensity or weight of the noise. It can be adjusted to control how strongly the noise affects the latent image, with higher values leading to more pronounced noise effects.

k

This float parameter further modifies the noise characteristics, potentially affecting its distribution or pattern. Adjusting k can lead to different visual outcomes in the generated images.

latent_image

This is the input latent image to which noise will be added. It serves as the base representation that the node manipulates to produce varied outputs.

noise_strength

This parameter controls the overall strength of the noise applied to the latent image. It acts as a multiplier, with higher values resulting in more significant noise influence.

normalize

When set to true, this parameter normalizes the noise to match the mean and standard deviation of the latent image. This ensures that the noise is applied in a balanced manner, maintaining the original image's statistical properties.

latent_noise

An optional parameter that allows you to provide a pre-generated noise sample. If specified, this noise will be used instead of generating new noise based on the other parameters.

mask

This optional parameter can be used to specify areas of the latent image where noise should or should not be applied. It provides additional control over the noise application, allowing for targeted effects.

LatentNoised Output Parameters:

samples

The primary output of the LatentNoised node is the modified latent image samples. These samples reflect the original latent image with the applied noise, ready for further processing or generation tasks. The output can vary significantly based on the input parameters, offering a wide range of creative possibilities.

LatentNoised Usage Tips:

• Experiment with different noise_type settings to discover unique visual effects and styles in your generated images.
• Use the noise_seed parameter to reproduce specific noise patterns, which is helpful for iterative design processes or when sharing results with others.
• Adjust alpha and k to fine-tune the noise characteristics, balancing between subtle variations and dramatic transformations.

LatentNoised Common Errors and Solutions:

"Noise type not supported"

• Explanation: The specified noise_type is not recognized by the node.
• Solution: Ensure that the noise_type is one of the supported options. Check the documentation for a list of valid noise types.

"Invalid noise seed"

• Explanation: The noise_seed provided is outside the acceptable range.
• Solution: Use an integer value within the valid range for the noise_seed parameter, typically between 0 and 0xffffffffffffffff.

"Latent image not provided"

• Explanation: The latent_image input is missing or invalid.
• Solution: Ensure that a valid latent image is supplied to the node as input. Check the format and structure of the latent image data.
