BinaryMorphologicalOperation¶
Performs morphological operations on an input image channel
Description¶
This application performs binary morphological operations on a mono band image or a channel of the input.
Parameters¶

Examples¶
From the command-line:
otbcli_BinaryMorphologicalOperation -in qb_RoadExtract.tif -out opened.tif -channel 1 -xradius 5 -yradius 5 -filter erode
From Python:
import otbApplication
app = otbApplication.Registry.CreateApplication("BinaryMorphologicalOperation")
app.SetParameterString("in", "qb_RoadExtract.tif")
app.SetParameterString("out", "opened.tif")
app.SetParameterInt("channel", 1)
app.SetParameterInt("xradius", 5)
app.SetParameterInt("yradius", 5)
app.SetParameterString("filter","erode")
app.ExecuteAndWriteOutput()
