+As it could be seen, as predictable and quite obvious, the Disparity map has got some problems above the sea, it is possible to obtain only a diffused noise, whereas in the other areas a good disparity map is obtained.
+
+To date, it is therefore possible to achieve disparity maps starting from a tri-stereo dataset.
+
+I have seen that there are some issues in the epipolar constraint in morphologically complex areas: I'm planning to fix this in the next weeks, after a deep analysis of the problem. Furthermore I'm planning to spend some time scrubbing the Plug-in since I think it needs a better structure for the classes created.
