Weekly Report 1 (2015, May 31)

WHAT I GET DONE THIS WEEK:

I have prepared the wiki page (​http://trac.osgeo.org/ossim/wiki/GSoC_2015) and the Git repository (​https://github.com/martidi/opencv_dsm) for code hosting.

I have scrubbed the Plug In developed last year in order to facilitate the deployment of the new funcionalities that I have planned to implement.

I have configured a new IDE for a better management of the source code (Qt Creator).

I have worked (and I am still working) on a new version of matching for epipolar imagery generation, since I have noticed that the old one had some effectiveness problem in finding good Tie Points: I am switching from a SIFT-oriented matching to a Area Based one.

I have deployed an images preprocessing Wallis filter (Baltsavias version) to enhance the local contrast throughout the image, while reducing the overall contrast between bright and dark areas, in order to improve the subsequent dense matching.

WHAT I PLAN ON DOING NEXT WEEK:

To continue working on the automatic TPs generation.

To implement tri-stereo projection.

To test and control implementation efficacy – discuss results with mentors.

SOMETHING ON WHICH I AM BLOCKED:

At the moment I am not blocked on anything.

Weekly Report 2 (2015, June 07)

WHAT I GET DONE THIS WEEK:

I have worked (and I am still working) on a new version of matching for epipolar imagery generation, trying to implement a new and effective way able to generate epipolar images.

I have begun to implement a tri-stereo projection for triplet input images.

WHAT I PLAN ON DOING NEXT WEEK:

To solve the problems on which I am stuck.

To continue working on epipolar images generation.

To finish tri-stereo projection implementation.

To test and control implementation efficacy – discuss results with mentors.

SOMETHING ON WHICH I AM BLOCKED:

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

Weekly Report 3 (2015, June 14)

WHAT I GET DONE THIS WEEK:

I have worked (and I am still working) on a new version of matching for epipolar imagery generation, trying to implement a new and effective way able to generate epipolar images. Mentors (with community support) have suggested me to have a look to an OSSIM stand-alone executable (ossim-autreg) that seems to have some functionalities suitable to fix this issue.

I have implemented a tri-stereo projection for triplet input images (​https://github.com/martidi/opencv_dsm/tree/triplet).

WHAT I PLAN ON DOING NEXT WEEK:

To solve the problems on which I am stuck.

To continue working on epipolar images generation and analyze ossim-autreg executable.

To test and control implementation efficacy – discuss results with mentors.
