Image segmentation is an extremely wide topic of Computer Vision. Its definition is not univocal and is therefore commonly expressed in very generic terms, like "a process aimed to partition an image in regions which are homogeneous with respect to given visual properties". Furthermore, image segmentation is often confused with the contour detection problem. This is due to the lack of a clear cut between these two specular topics. Applicability to a large variety of domains, like remote sensing, security, automation and medical imaging, to mention a few, has contributed to enlarge the set of different solutions available in literature.

The GRIP team has expereinced the design of image segmentation algorithms for different applications since '99. In this page you can found demos, codes and references of some representative GRIP projects on image segmentations:

• MR-EMF, Multi-Resolution Edge, Mark and Fill algorithm: it is particular version of the watershed-based method EMF, specifically designed for multi-resolution remote sensing images, like Ikonos, GeoEye, WorldView.
• TFR, Texture Fragmentation and Reconstruction algorithm.

It follows a complete list of the GRIP publications on image segmentation.
