I have a raster image containing values ranging from 1 to 10 in Integer format.

I want to count the number of pixel with value = 1.

Is there any method in Arcpy which returns the pixel count if given raster and value as input?


Use the Build Raster Attribute Table tool, then a SearchCursor.

values = {}
arcpy.BuildRasterAttributeTable_management(your_raster, "Overwrite")
with arcpy.da.SearchCursor(your_raster, ['VALUE', 'COUNT']) as rows:
    for row in rows:
        values[row[0]] = row[1]
print values.get(12345, 0)
  • Thanks, @Luke was I was struggling with numpy I got the answer but it took a lot of time!. This is simple and faster. Thank you once again. Jan 5 '16 at 9:12
