| Usage | Example with default values |
Inputs| Name | Type | Mandatory | Description |
|---|---|---|---|
| images | ImageList | Mandatory | A directory with grayscale image files. |
| objects | CSV | Mandatory | List of locations for the objects. |
| names | ImageList | Optional | A directory with the original image files, for naming the table. If omitted, names from "dir" are used. |
Outputs| Name | Type | Description |
|---|---|---|
| out | CSV | Intensity features. |
Parameters| Name | Type | Default | Description |
|---|---|---|---|
| erodeWidth | float | 30 | Erosion width to calculate margination in pixels or percentage of object length. Erosion width can be negative, which means the object will be dilated. |
| isRatio | boolean | true | Eroding width is expressed in percentage of object width instead absolute pixels. |
| overlap | boolean | false | Calculate object overlap percentage. (Very slow). With this feature also Margination with negative erosion is calculated more acurately, so that the outer intensity does not cross other objects' insides. |
| prefix | string | " " | Prefix string for margination headers in the result table. Used when reading the same images with multiple parameters and the joining the results. |
