 At the moment I have some issues in finding the proper epipolar model, but I am pretty confident to being able to find soon a suitable solution.

+=== Weekly Report 6 (2015, July 05) ===
+
+
+WHAT I GET DONE THIS WEEK:
+
+I have finalized the midterm evaluation.
+
+I have begun to implement disparity map fusion: starting from two disparity maps (obtained from the 3 images processed) I would like to obtain a single disparity map resulting from a clever fusion of the two previous maps. I thought to get the mean disparity value from the two maps for each (i,j) position if the difference between the two maps is under a threshold, otherwise, if the difference is higher, I get the value closest to the reference DSM used for the initial projection, moreover where there is a no data value I get the other disparity map result.  
+
+Following advice from mentors and community, in order to improve automatic TPs identification enabling a more homogeneous points detection, I have implemented a new OpenCV class able to find detectors for a source image divided into a grid and able to detect points in each cell. As you can see from the image below, results seems enough satisfying.
+
+I'm trying to solve the epipolar issue. 
+
+[[BR]]
+WHAT I PLAN ON DOING NEXT WEEK:
+
+To solve the problems on which I am stuck.
+
+To continue implementing disparity map fusion and filtering.
+
+To test and control implementation efficacy – discuss results with mentors.
