Dear Ghassem, OTB do not provide a fully integrated environment for object-orientated classification, but several bricks you put together to build a processing chain.
You're right, the strength of the object-oriented approach is to mix spectral, spatial, and contextual attributes during the classification process. In my understanding there is no straight-forward solution in OTB at the moment. What you can do is to produce a multi-band image including your spectral bands, but also new pseudo-bands describing textural or geometrical characteristics, and then run the process I described above. 2017-03-02 15:41 GMT+01:00 <[email protected]>: > Shouldn't we use spectral, spatial, and contextual attributes of our > objects (segments) while we are classifying our image?
