| method | dropdown | sobel | Edge detection operator: sobel, prewitt, laplacian, or log (Laplacian of Gaussian) |

| sigma | FLOAT | 1.0 | Gaussian smoothing sigma used only for the LoG operator (0.1–10.0) |

## Limitations
|

## Notes
|
||||
|
||||
- sigma is ignored for sobel, prewitt, and laplacian methods.
|
||||
- Sobel and Prewitt return gradient magnitude; Laplacian and LoG return signed second-derivative values.
