RegionPixelCount

Summary

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.

Syntax

RegionPixelCount(raster, {maximum_region_size}, {pixel_neighborhood})

Parameter	Explanation	Data Type
raster	The input raster.	Raster
maximum_region_size	The maximum number of pixels a region can contain. The default value is 100.	Integer
pixel_neighborhood	The number of neighborhoods used to assess pixel connectivity. Valid values are 4 and 8. The default value is 4.	Integer

Return value

Data Type	Explanation
Raster	The output raster.

Code sample

RegionPixelCount example

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')
