To upsize a picture, use the B-spline algorithm

If you take a low-res picture, and you want to blow it up to a higher size, there are different algorithms to do the calculation of all those new pixels. I talked about this earlier in “How to upsize an image“. I went a bit further now and took a 100×100 pixels detail of a Roos Van Acker picture by Filip Naudts and enlarged it five times: to 500×500. The tool I use, Irfanview, has 6 algorithms to do resize:
Upsize picture from 100x100 to 500x500

Contrary to what I expected, it was not the Lanczos filter (slowest and ‘best’) that gave the best results, but the B-spline algorithm that’s supposedly a bit worse. With Lanczos you get an rastering effect (check her hair), with B-spline it’s more even.
