Synthèse
Groups connected regions with the same pixel value and calculates the number of pixels in each region.
Discussion
For more information on how this function works, see the Region Pixel Count 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.
Syntaxe
RegionPixelCount (raster, {maximum_region_size}, {pixel_neighborhood})
Paramètre | Explication | Type de données |
raster | The input raster. | Raster |
maximum_region_size | The maximum number of pixels a region can contain. (La valeur par défaut est 100) | Integer |
pixel_neighborhood | The number of neighborhoods used to assess pixel connectivity. Valid values are 4 and 8. (La valeur par défaut est 4) | Integer |
Type de données | Explication |
Raster |
The output raster. |
Exemple de code
This example calculates the number of pixels in each region.
from arcpy.ia import *
pixel_count_raster = RegionPixelCount('C:/arcpyExamples/ndvi_threshold.tif', 1000, 4)
pixel_count_raster.save('C:/temp/ndvi_mask.tif')
