Inputs| Name | Type | Mandatory | Description |
|---|---|---|---|
| images | ImageList | Mandatory | A directory with grayscale or BW image files. |
| seed | ImageList | Optional | A directory of seed masks, used in Voronoi method. |
Outputs| Name | Type | Description |
|---|---|---|
| mask | ImageList | BW PNG cut mask images. |
| lines | ImageList | BW PNG images of the lines used for watershed. |
| perimeter | ImageList | BW PNG images of the perimeter of the mask. |
Parameters| Name | Type | Default | Description |
|---|---|---|---|
| blur | int | 0 | Sigma of gaussian filter for blurring the images. 0 to disable. Applicable to ds and ws methods. |
| invert | boolean | false | Invert image before watershed. |
| maxArea | int | 0 | Maximum accepted pixel area in all methods. Use 0 for no limit. |
| method | string | "ds" | Method for image watershed. Choose from 'ds', 'ws', 'vo', 'de'. |
| minArea | int | 0 | Minimum accepted pixel area in all methods. Works only with BW mask images. |
| sharpen | int | 0 | Sigma of gaussian filter for sharpening the images via unsharp mask. 0 to disable. |
