imagecalc.calcMultiImgBand Stas example

[Konstantinos Sideris]

Hello

I am trying to compile a script with imagecalc.calcMultiImgBandStats.

Is there an example oh how you can script it?

I have tried several times creating an example for calculating the algorithm for some images but I get the error _imagecalc.error: Could not open image 0

Hers what I have written so far:

import rsgislib

from rsgislib import imagecalc

inputImages = '/home/2005/'

outputImage = '/home/Outputs/Result.kea'

summaryStatOption = rsgislib.SUMTYPE_MEDIAN

gdalFormat = 'KEA'

datatype = rsgislib.TYPE_32FLOAT

imagecalc.calcMultiImgBandStats(inputImages,outputImage,summaryStatOption,

                                                       gdalFormat,datatype)

Hi,

You need to provide a list of images to the function, not a directory. You can use glob to list all the files in a directory matching ‘*.kea’, this should work.

For example:

import glob

import rsgislib
from rsgislib import imagecalc

inputImages = glob.glob('/home/2005/*kea’)

outputImage = '/home/Outputs/Result.kea'
summaryStatOption = rsgislib.SUMTYPE_MEDIAN
gdalFormat = 'KEA'
datatype = rsgislib.TYPE_32FLOAT
imagecalc.calcMultiImgBandStats(inputImages,outputImage,summaryStatOption,
                                                       gdalFormat,datatype)

Thanks,

Dan
