We will use the tool to calculate the image textures for a subset of a pan-
chromatic aerial photograph that covers a coniferous forest, pasture land and some
hedgerows Fig. 13.11 . We run the tool as follows and calculate the simple texture
features:
otbcli_HaralickTextureExtraction -in ap_subset.tif
-parameters.xrad 2 -parameters.yrad 2 -parameters.xoff 1
-parameters.yoff 1 -texture simple -out
ap_subset_simple.tif uint16
