Comparing Neural Networks, Invariant Moments and Mathematical Morphology Performances for the Automatic Object Recognition

Pattern recognition is an essential part of any high-level image analysis system. The CRPSM, in the framework of the European Projects GMOSS and GMOSAIC, has developed some techniques able to automatically recognize and extract potential made-man structures which could be present in complex aerial and satellites images. In particular, this paper aims at describing several of the developed techniques which allow the automatic detection of given objects of interest. These techniques are based on different approaches, therefore the results provided by them are compared and the their advantages and disadvantages are highlighted. The purpose described above is obtained by using several algorithms developed by CRPSM in the last few years based on the Mathematical Morphology, Geometrical Moment Invariant and Neural Networks approaches.
