Workshop setup


The intention of the organizers is to provide a stimulating casual workshop 
environment, rather than a rigid conference climate, in order to promote
meaningful discussions beyond the presentations.  

The workshop will take place at the campus of the Technion - Israel Institute
of Technology, which is located on the Carmel Mountain, by the Mediterranean,
and provides a magnificent view on Haifa Bay, the northern part of Israel and
the Galilee Mountains. 


Workshop topics


The main objectives of the workshop are the investigation and analysis of
theoretical and practical aspects of feature extraction, surface
reconstruction, object extraction and their interactions.


Topics include (but not limited to):


Theoretical topics:

* Surface reconstruction methods
* Surface reconstruction from laser scanner data
* Data fusion (multi*sensor, multi-spectral, multi-temporal)
* Combined feature extraction and surface reconstruction algorithms
* Surface reconstruction aspects of automatic scene analysis
* Impact of scale and radiometric/geometric image formation on features and
  surfaces
* 2D and 3D grouping
* Modeling of natural and man-made objects for surface and 3D object extraction
* Performance evaluation for surfaces and objects
* Error detection in automatically generated surfaces


Practical topics:

* Automatic image orientation
* automatic DEM generation
* Automatic and semiautomatic tools for editing DEM
* Orthophoto and mosaic generation
* GIS*data extraction and updating
* Visualization methods
* Products derived from surfaces
* Advances in digital photogrammetric workstations
