# NormalizeImages - ComfyUI Built-in Node Documentation

> Complete documentation for the NormalizeImages node in ComfyUI. Learn its inputs, outputs, parameters and usage.

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     |
