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	Data Type	Required	Range	Description
image	IMAGE	Yes	-	The input image to be normalized.
mean	FLOAT	No	0.0 - 1.0	The mean value to subtract from the image pixels (default: 0.5).
std	FLOAT	No	0.001 - 1.0	The standard deviation value to divide the image pixels by (default: 0.5).

Outputs

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