Divisive issue 4:
Influence of context/state

What information (context) is carried forward?
How much does it influence processing?

·   All systems use continuity in time

- current features extend existing objects

·   Can observations have radically different interpretations?

- noise band is one object or more (Ellis)

·   Low level processing which depends on high-level

- grouping (Kashino)
- parameterization (Weintraub)
- actual feature extraction (Klassner)
