Summary
Groups adjacent pixels depending on the specified radius from the seed point.
Discussion
For more information about how this function works, see the Region Grow raster function.
The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.
Syntax
RegionGrow (raster, seed_points, max_growth_radius_field, similarity_threshold_field, {fill_value_field})| Parameter | Explanation | Data Type |
raster | The input raster. | Raster |
seed_points | The point feature class, serving as the initial seeds for the algorithm. Each seed point corresponds to one entry in the attribute table, which includes values for the maximum growth radius, similarity threshold, and an optional fill value. | String |
max_growth_radius_field | The field in the attribute table that defines the maximum growth radius, in the image's spatial reference units. | String |
similarity_threshold_field | The field that defines the similarity threshold, as Euclidean distance in spectral space. | String |
fill_value_field | The field that defines the fill value for the group of pixels formed from each seed point. In a multiband image, all bands will be assigned this value. (The default value is None) | String |
| Data Type | Explanation |
| Raster | The output raster. |
