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:
* API to tune heuristics values * The next post explaining the remaining of B-Splines extraction
