The OTB adapters will be improved in terms of:
Product format compatibility,
Installation and configuration
At the moment OTB adapters are working but they are not as easy to work with as native operators:
They work with images saved on the disk, a product has to be explicitly saved (eg. as GeoTiff) to be usable by these operators,
The output is not always automatically opened after the process is finished, for example shapefiles needs to be added to the product "by hand" after applying segmentation.
