# SeedVR2PostProcessing - ComfyUI Built-in Node Documentation

> Complete documentation for the SeedVR2PostProcessing node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node aligns the generated image with the original resized image and applies optional color correction. It takes the output from a SeedVR2 upscaling process and adjusts it to match the colors and dimensions of the original reference image.

## Inputs

| Parameter                 | Description                                                                                                                                                                                                                                                                                                                                              | Data Type | Required | Range                                                 |
| ------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ----------------------------------------------------- |
| `images`                  | The generated image to process.                                                                                                                                                                                                                                                                                                                          | IMAGE     | Yes      | -                                                     |
| `original_resized_images` | The original resized image before pre-processing, used as reference.                                                                                                                                                                                                                                                                                     | IMAGE     | Yes      | -                                                     |
| `color_correction_method` | Method to match the generated image colors to the original image. lab: transfer color in CIELAB space, preserving detail (most faithful). wavelet: transfer low-frequency color, keeping upscaled high-frequency detail. adain: match per-channel mean/std (fastest, global tint). none: skip color transfer (geometry alignment only). (default: "lab") | COMBO     | Yes      | `"lab"`<br />`"wavelet"`<br />`"adain"`<br />`"none"` |

**Note:** The `images` and `original_resized_images` inputs must have matching dimensions. If the original image has an alpha channel (4 channels), it will be preserved and applied to the output.

## Outputs

| Output Name | Description                                                                                      | Data Type |
| ----------- | ------------------------------------------------------------------------------------------------ | --------- |
| `images`    | The processed image with color correction applied and dimensions aligned to the reference image. | IMAGE     |
