What is eCognition and how does it work?
eCognition classifies and analyzes imagery, vectors and point clouds using all the semantic information required to interpret it correctly. Rather than examining stand-alone pixels or points, it distills meaning from the objects’ connotations and mutual relationships, not only with neighboring objects but throughout various input data.

How to select image object level in eCognition?
Level: If you choose image object level as domain, you must select an image object level name or a variable. If you choose pixel level as domain, you can specify the name of a new image object level. Class filter: If you already classified image objects, you can select classes to focus on the image objects of these classes.
How is hierarchical classification used in eCognition 4?
The Hierarchical Classification algorithm is used to apply complex class hierarchies to image object levels. It is backwards compatible with eCognition 4 and older class hierarchies and can open them without major changes. The algorithm can be applied to an entire set of hierarchically arranged classes.
