NormalizeImages - ComfyUI Built-in Node Documentation - ComfyUI

This node adjusts the pixel values of an input image using a mathematical normalization process. It subtracts a specified mean value from each pixel and then divides the result by a specified standard deviation. This is a common preprocessing step to prepare image data for other machine learning models.

Inputs

Parameter	Description	Data Type	Required	Range
`image`	The input image to be normalized.	IMAGE	Yes	-
`mean`	Mean value for normalization (default: 0.5).	FLOAT	No	0.0 - 1.0
`std`	Standard deviation for normalization (default: 0.5).	FLOAT	No	0.001 - 1.0

Outputs

Output Name	Description	Data Type
`image`	The resulting image after the normalization process has been applied.	IMAGE
