Zusammenfassung
Groups connected regions with the same pixel value and calculates the number of pixels in each region.
Diskussion
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.
Syntax
RegionPixelCount (raster, {maximum_region_size}, {pixel_neighborhood})
Parameter | Erläuterung | Datentyp |
raster | The input raster. | Raster |
maximum_region_size | The maximum number of pixels a region can contain. (Der Standardwert ist 100) | Integer |
pixel_neighborhood | The number of neighborhoods used to assess pixel connectivity. Valid values are 4 and 8. (Der Standardwert ist 4) | Integer |
Datentyp | Erläuterung |
Raster |
The output raster. |
Codebeispiel
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')
