  Hi everyone.

As Hamish already posted, I am working on Object Based Image Analysis 
for my PhD.
I have developed a system based on mseg 
(http://sourceforge.net/projects/mseg/) for image segmentation, CLIPS 
for rule based classification and Support Vector Machines for supervised 
classification. I also use OpenCV for some advanced computer vision 
algorithms. All these programs are combined through scripts and have 
primitive CLI interfaces.
I have published some papers around this technology and I will release 
all my code under GPL soon.

Especially for the segmentation algorithm, it is still unoptimized for 
speed, but gives good results (of course it has to be improved a lot to 
meet my expectations...). It is written in C++ and is missing gdal 
integration right now (works only with ER-Mapper ers - BIL format) with 
my own implementation of image I/O. Initially I had in mind to include 
it on GRASS someday, but I will need support to know the internals of
