The Region Grow function groups neighboring pixels into groups depending on the specified radius from the seed point. The group of pixels or object is assigned a specified fill value.
This function is used within the Reclassifier functionality contained in the Classification Wizard. The Reclassifier functionality includes the user interface to collect the required input seed points.
The raster layer that you want to perform this function on.
A point feature layer, serving as the initial seeds for the algorithm. Each seed point corresponds to one entry in the attribute table, which carries the maximum growth radius, similarity threshold, and fill value information.
Max Growth Radius Field
The field in the attribute table that defines the maximum growth radius, in the image's spatial reference units.
Similarity Threshold Field
The field in the attribute table that defines the similarity threshold, as Euclidean distance in spectral space.
Fill Value Field
The field in the attribute table that defines the fill value for the group of pixels. In a multiband image, all bands will be assigned this value.
