Krzysztof and Jabiertxo,

thanks for the hints. I talked to Nathan and he also hinted one direction to go.

I delayed this task for later and I started to learn linear algebra (two large topics in two days, only other two missing). Reasons to study linear algebra ASAP started to grow.

Reason #1


I'll have to use this knowledge to understand harmonic maps (step done after B-Splines optimization in Kopf-Lischinski) to fix the positions.

Reason #2


Chat piece copied without authorization, but it doesn't reveal any secrets, then I think there won't be any problems. ;)

(15:00:28) Vinícius dos Santos Oliviera: I was wondering this about the sparse pixels heuristic, but I thought there is no way to fix sparse pixels
(15:00:53) Vinícius dos Santos Oliviera: I think it could possible, somehow, to use dynamic programming in curves heuristic
(15:00:55) Nathan Hurst: there might be :)
(15:00:58) Nathan Hurst: yes
(15:01:07) Nathan Hurst: it feels a bit like eigenvalues
(15:01:13) Nathan Hurst: at the intuitive level
(15:01:37) Vinícius dos Santos Oliviera: I'll do a research about eigenvalues, thanks for the tip

Reason #3


I'll have a test on Monday.

In the meantime


I implemented some easy tasks on libdepixelize that don't takes too much time like:
