This question has been asked before as Using thematic layer for segmentation in eCognition?.
However, I have not been able to resolve the issue using the answer provided.
Can someone clarify the correct procedure?
I would like to restrict all segmentation and classification processes to take place within areas (polygons) covered by my thematic layer rather than the whole scene.
I have successfully carried out a chessboard segmentation using my thematic layer so the polygons from my thematic layer are now image objects. I then used the 'assign class' algorithm to assign those image objects to one class. I then attempted to carry out an additional segmentation at the image object level using the class filter to select my new class. However, the segmentation was still carried out on the entire scene.
The only instance where my steps have differed to those recommended at Using thematic layer for segmentation in eCognition? is when I was unable to see how to assign a class based on the "number of overlaps". I assigned my image objects to a single class without using "number of overlaps".
