An advantage of the developed OBIA framework is that it is composed of free (as
in freedom) software. For the implementation of this research a number of free and
open-source libraries were used (MSEG, cvAML, libSVM, OrfeoToolbox, and
GDAL). The coding was performed in the C++ and Python programming languages.
A disadvantage of the developed OBIA framework is that a knowledge-based
classification solution is not yet integrated but is currently being worked on.
Some of the topics for further research and development are extension of the
developed OBIA framework to integrate knowledge-based classification, solutions
for object-specific extraction tasks based on scale-space shape priors, and adaptation
of the developed methodology to specific remote sensing applications.
