I am attempting my first use of the modeler from the Graphical Modeler from the Processing menu in QGIS (2.18.3). I made a simple model for using meanshift segmentation. It just has a raster input and the algorithm for the segmentation.
I have several small rasters that I want to segment and so I want to run this iteratively through the rasters. I am not sure how that is done, so I am trying to run the model as a batch process. The batch parameters require me to name an output for each line. It seems tedious to have to write out a path and name for each output. I don't know how to simplify this. In ArcGIS' model builder, I add a generic name with an iterator to just number each new file. The iterator in that modeler is %i%. How should I use the process model to iterate through the list? Is batch processing the right way? How do I designate the names for the output without typing each out individually? I'd be fine if the process just referenced back to the raster names.
EDIT after Oto's answer. I don't get that menu from
