Program stops working

[hongyann]

Hello, I want to ask some help. My original data is from Lytro Illum. The setting part is shown in the figure. Micro image patch size: 7; refocusing range: -2, 4. But After the progress bar of Light filed aligment reaches 76%, it stoped. I am confused . Can you give me some suggestions?

Sure! Your probably found a bug :) Can you pls provide a link to your *.lfr and *.tar file? Then I can reproduce the issue on my side.

hey hongyann,

i have good news! i was able to reproduce the issue on my machine and did a fix which made the program run through without errors. your images revealed a problem in my centroid sort algorithm which i never encountered with my data. so, thanks for providing yours!

as of now (until i make a new release), the fixed version is only available in the develop branch. to get this working on your side, you need to clone/download from the develop branch which is found here:

https://github.com/hahnec/plenopticam/tree/develop

then, cd to the download directory, install with python3 setup.py install and run the tool with plenopticam -g from the command line. let me know if you come across further issues.

on a side note: with this version, i have added a feature to monitor errors by saving a file (err_log.txt) to the output folder next to your lfr file. this error report can be copy/pasted here and may help to trace issues in future.

the problem has been resolved. thank you!

I still have a question, that is, the generated refocused images are generally darker. Is this normal? or have problems with my settings?

[hahnec]

Can you pls post images/screenshots to illustrate the problem in the referenced issue #3

[hongyann]

left image is produce by your work, the right one is produce by another. I found the left image is more darker than another. Is it normal?

As this issue is closed, can you please re-post your above reply in issue #3 ? Thanks
