(deforum) Add Custom Noise Description

Introduce various noise types into images using PyTorch for creative AI art.

(deforum) Add Custom Noise:

The AddCustomNoiseNode is designed to introduce various types of noise into an image using PyTorch, enhancing the creative possibilities for AI artists. This node allows you to add custom noise to your images, which can be useful for generating unique textures, simulating different photographic effects, or preparing data for training machine learning models. By leveraging this node, you can control the type and amount of noise applied, providing a high degree of flexibility and creative control over the final output. This node is particularly beneficial for those looking to experiment with different noise patterns and their impact on image aesthetics.

(deforum) Add Custom Noise Input Parameters:


This parameter represents the input images to which the noise will be added. The images should be in a tensor format compatible with PyTorch. The quality and characteristics of the input images will directly influence the final output after noise application.


This parameter specifies the type of noise to be added to the images. Different noise types can produce varying effects, such as Gaussian noise, salt-and-pepper noise, or other custom noise patterns. The choice of noise type will significantly impact the visual outcome and can be used to achieve specific artistic effects.


This parameter controls the intensity or amount of noise to be added to the images. It is a floating-point value where higher values result in more pronounced noise. The default value is typically set to a moderate level, but you can adjust it to achieve the desired level of noise. The minimum and maximum values depend on the specific implementation and noise type.


This optional parameter allows you to set a seed for the random noise generation process. By providing a seed value, you can ensure that the noise pattern is reproducible, which is useful for consistent results across different runs. If not provided, the noise will be generated randomly each time.


This optional parameter can be used to provide a temperature map that influences the noise application. The temperature map can add another layer of control, allowing for more complex and varied noise patterns based on the temperature values. This parameter is particularly useful for advanced users looking to create intricate noise effects.

(deforum) Add Custom Noise Output Parameters:


This output parameter represents the image after the custom noise has been applied. The noised image retains the original content but with the added noise, resulting in a modified version that can be used for various artistic or technical purposes.


This output parameter provides the actual noise that was generated and applied to the image. This can be useful for analysis, debugging, or further processing, allowing you to understand the noise characteristics and how they affect the final image.

(deforum) Add Custom Noise Usage Tips:

  • Experiment with different noise_type values to see how various noise patterns affect your images. This can help you discover unique textures and effects.
  • Adjust the amount parameter incrementally to find the optimal level of noise for your specific use case. Too much noise can overwhelm the image, while too little may not produce the desired effect.
  • Use the seed parameter to generate consistent noise patterns across multiple images or runs. This is particularly useful for creating a cohesive series of images with similar noise characteristics.
  • If you are looking for more complex noise effects, consider using the temperature_map parameter to add another layer of control over the noise application.

(deforum) Add Custom Noise Common Errors and Solutions:

"Input images tensor is not on the same device as noise tensor"

  • Explanation: This error occurs when the input images tensor and the noise tensor are not on the same device (e.g., one is on the CPU and the other is on the GPU).
  • Solution: Ensure that both the input images tensor and the noise tensor are on the same device before applying the noise. You can use the .to(device) method in PyTorch to move tensors to the desired device.

"Invalid noise type specified"

  • Explanation: This error occurs when an unsupported or incorrect noise type is specified in the noise_type parameter.
  • Solution: Verify that the noise_type parameter is set to a valid noise type supported by the node. Refer to the documentation or code comments for a list of acceptable noise types.

"Amount parameter out of range"

  • Explanation: This error occurs when the amount parameter is set to a value outside the acceptable range.
  • Solution: Check the acceptable range for the amount parameter and ensure that the value you provide falls within this range. Adjust the value accordingly to avoid this error.

"Seed value must be an integer"

  • Explanation: This error occurs when the seed parameter is not an integer.
  • Solution: Ensure that the seed parameter is set to an integer value. If you are generating the seed programmatically, use functions that return integer values.
