Hi fellow devs (and users following the progress of libdepixelize),
I've been coding the B-Splines optimization code for the last several few days and I was struggling to make any progress at all. I've tried SOOO many techniques, but nothing would do. Anyway, I realized that the paper states "... by optimizing the locations of their control points". I was trying to optimize the location of all points (not only control points.
Sorry for the useless email, but I just wanted to share my frustration. I'll be uploading the (hopefully) working code today. I'll need to refactor a lot of the shitty code I created.
