ComfyUI Node: Batch Average Image

Batch Average Image:

The BatchAverageImage node is designed to process a batch of images and compute either the mean or median image from the batch. This node is particularly useful for AI artists who want to create a composite image that represents the average characteristics of a set of images. By averaging the images, you can achieve a smoothing effect that reduces noise and highlights common features across the batch. This can be beneficial for tasks such as style transfer, image denoising, or creating artistic effects that blend multiple images into a cohesive whole.

Batch Average Image Input Parameters:

images

This parameter expects a batch of images as input. The images should be in a tensor format, typically with dimensions representing the batch size, height, width, and color channels. The batch of images is the primary data that will be processed to compute the average image.

operation

This parameter determines the type of averaging operation to be performed on the batch of images. It accepts two options: mean and median. The mean option calculates the average pixel value across all images in the batch, resulting in a smooth and blended image. The median option computes the median pixel value, which can be more robust to outliers and preserve edges better than the mean. Choose the operation based on the desired effect for your composite image.

Batch Average Image Output Parameters:

IMAGE

The output is a single image that represents the average of the input batch of images. Depending on the chosen operation (mean or median), the resulting image will either be a smooth blend or a robust composite that highlights common features while reducing noise. This output can be used for further processing or as a final artistic product.

Batch Average Image Usage Tips:

• Use the mean operation to create a smooth and blended composite image that reduces noise and highlights common features across the batch.
• Use the median operation to preserve edges and details better than the mean, especially when dealing with images that have significant outliers or noise.
• Ensure that all images in the batch have the same dimensions and color channels to avoid errors during processing.

Batch Average Image Common Errors and Solutions:

Mismatched image dimensions

• Explanation: The images in the batch have different dimensions or color channels.
• Solution: Ensure that all images in the batch have the same height, width, and number of color channels before passing them to the node.

Invalid operation type

• Explanation: The operation parameter is set to a value other than mean or median.
• Solution: Set the operation parameter to either mean or median to specify the type of averaging operation to be performed.

Empty image batch

• Explanation: The input batch of images is empty or not provided.
• Solution: Provide a valid batch of images with at least one image to the node for processing.
