Map-aided structural analysis of aerial images
A syntax oriented method for a map-aided analysis of structures
in aerial images is proposed.
At first the map must be analysed in order to obtain a suitable
representation of its knowledge content.
A special kind of graph, a so-called image-description graph
is the result of this map analysis.
The knowledge of the map represented on different description levels
is used to control the image analysis process.
Based on this knowledge, expectations for attribute values of image objects
are defined.
Generated objects are assessed relative to the expectations
of the map and the object model.
A set-oriented selection method is applied to deduce
the processing priority using these two assessments.
Expected objects are preferably processed
for building up more complex objects.
Thus the map-aided analysis can be used to reduce
processing time for the verification.
