    115115I'm trying to use an ASCII DEM file as input for the elevation data, but I have had some issues with it.

     124WHAT I GET DONE THIS WEEK:
     125
     126I have deeply studied how to implement the epipolar rectification (goal of the mid-term). As a result of a discussion with mentors, I have evaluate alternative approaches for the epipolar rectification, such as Vertical Line Locus feature-based type approach, Vertical Line Locus based on a coarse external DSM (such as SRTM or ASTER) and integration of Disparity Map and Non-Disparity Map approaches.
     127
     128As a result of a discussion with mentors, I have discarded the idea of using OpenCV SIFT procedure for automatic TPs generation since it cannot be included or used as part of a public distribution, and I have choosen another detector (OrbFeatureDetector). Therefore I have wrote a procedure for the automatic Tps detection with OrbFeatureDetector implemented in the OpenCV library and I have tested it on an Ortho Ready GeoEye stereo-pair: these are very good images since they are basically epipolar as already projected by provider on a constant ellipsoidical height.

     132
     133I have wrote a procedure for the implementation of the Semi Global Matching algorithm and the Disparity Map generation; I have tested it on the above-mentioned images and I have calculated the x and y parallax errors.

     137I have upload the code produced on Git repository (https://github.com/martidi/OSSIM-GSoC-2014).

     140WHAT I PLAN ON DOING NEXT WEEK:
     141
     142To solve the problem on which I am stuck.
     143
     144To continue working on epipolar images generation and Disparity Map creation.
     145
     146To test and control implementation efficacy – discuss results with mentors.

     149SOMETHING ON WHICH I AM BLOCKED:
     150
     151I am having some issues in the integration between OpenCV algorithms and OSSIM Apps.
