Weekly Report 1 (29th May, 2016)

WHAT I GET DONE THIS WEEK:

I scrubbed and thoroughly restructured all the code written last year in order to facilitate the creation of new classes aimed to the deployment of the new functionalities that I have planned to implement.

I worked (and I am still working) on the workflow for SAR imagery: as a matter of fact SAR images require a different managing with respect to the optical ones. So far it is possible to open TerraSAR imagery within DATE plug-in.


WHAT I PLAN ON DOING NEXT WEEK:

To complete the workflow for SAR imagery.

To begin the implementation of the complete automatization of the pyramidal approach.

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 (05th June, 2016)

WHAT I GET DONE THIS WEEK:

I have completed the workflow for processing TerraSAR images: at the moment, after an external tiff image file creation from the xml file, it is feasible to automatically process TerraSAR images and generate a DSM from them.

I have begun the implementation of the complete automatization of the pyramidal approach. I still have some issues related to the automatic re-opening of the freshly generated DSM: to switch from a resolution level to the following it is necessary to access the last generated DSM and use it as coarse DSM for re-projection.


WHAT I PLAN ON DOING NEXT WEEK:

To complete the implementation of the complete automatization of the pyramidal approach.

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


SOMETHING ON WHICH I AM BLOCKED:

At the moment I have some issues related to the automatic re-opening of DSM generated at the current resolution level, which has to be used as a coarse DSM for the next level for image re-projection.


Weekly Report 3 (12th June, 2016)

WHAT I GET DONE THIS WEEK:

I have continued working on the complete automatization of the pyramidal approach: thanks to my mentors's help, I have found a proper way to cope with this issue, but it still doesn't work for a compiling problem I think I will fix in the next few days.

I have begun working on the automatic mask creation for lay-over areas in SAR imagery: so far, I have created a routine able to create simulated images from raw images and exploiting the coarse dsm information. Starting from that, I'm going to create a mask to cross out lay-over areas.


WHAT I PLAN ON DOING NEXT WEEK:

To complete the implementation of the automatization of the pyramidal approach.

To continue working on automatic mask creation for lay-over areas in SAR imagery.

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

To fix bugs and review code.

To draft the mid-term report.


SOMETHING ON WHICH I AM BLOCKED:

At the moment I have some issues related to OSSIM compiling from the new repository, but I'm pretty sure I will fix it in the next few days.


Weekly Report 4 (19th June, 2016)

WHAT I GOT DONE THIS WEEK:

I have finished working on the complete automatization of the pyramidal approach: thanks to my mentors's help, I have found a proper way to solve this issue and now it works fine.

I have fixed the issue related to OSSIM compiling.

I have continued working on the automatic mask creation for lay-over areas in SAR imagery.

I have begun drafting the mid-term report.


WHAT I PLAN ON DOING NEXT WEEK:

To finalize and submit the mid-term report.

To fix bugs and review code.


SOMETHING ON WHICH I AM BLOCKED:

At the moment I am not blocked on anything.


Weekly Report 5 (26th June, 2016)

WHAT I GOT DONE THIS WEEK:

I have finalized and submitted the mid-term report.

I have fixed bugs and reviewed code.

I have attended the 36th EARSeL Symposium in Bonn presenting last year GSoC work and its development.


WHAT I PLAN ON DOING NEXT WEEK:

To continue working on the automatic mask creation for lay-over areas in SAR imagery.

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 5 (3rd July, 2016)

WHAT I GOT DONE THIS WEEK:

I have begun the implementation of a merging phase between different disparity maps: as a matter of fact, I've decided to shift the merging phase from DSM to disparity map. I'm testing a Total Generalized Variation approach, with different weights to the disparity maps according to lay-over areas present on the images.


WHAT I PLAN ON DOING NEXT WEEK:

To continue working on disparity merging.

To continue working on the automatic mask creation for lay-over areas in SAR imagery, in order to bring the app created outside DATE (in the OSSIM apps directory) inside the code core.

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.
