# LatentOperationSharpen - ComfyUI Built-in Node Documentation

> The LatentOperationSharpen node creates a sharpening operation for latent representations using a Gaussian kernel.

The LatentOperationSharpen node creates a sharpening operation for latent representations using a Gaussian kernel. It normalizes the latent data, applies a custom sharpening kernel through convolution, and then restores the original luminance. This enhances the details and edges in the latent space representation.

## Inputs

| Parameter        | Description                                                                                               | Data Type | Required | Range    |
| ---------------- | --------------------------------------------------------------------------------------------------------- | --------- | -------- | -------- |
| `sharpen_radius` | The radius of the sharpening kernel, which controls the size of the area used for sharpening (default: 9) | INT       | Yes      | 1-31     |
| `sigma`          | The standard deviation of the Gaussian kernel used to build the sharpening kernel (default: 1.0)          | FLOAT     | Yes      | 0.1-10.0 |
| `alpha`          | The sharpening intensity factor; higher values produce a stronger sharpening effect (default: 0.1)        | FLOAT     | Yes      | 0.0-5.0  |

All three inputs are advanced parameters and have default values, so the node can be used without changing them. This node is marked as experimental.

## Outputs

| Output Name | Description                                                       | Data Type         |
| ----------- | ----------------------------------------------------------------- | ----------------- |
| `operation` | Returns a sharpening operation that can be applied to latent data | LATENT\_OPERATION |
