# Post-Process SeedVR2 Output

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

| ----------- | ------------------------------------------------------------------------------------------------ | --------- |
| `images`    | The processed image with color correction applied and dimensions aligned to the reference image. | IMAGE     |
