software update: multipoint alignment and Theophilus
So I've been whiling away the last few days on a major overhaul to ppmcentre, including name change for the package and a few new features.
The most important new feature will be "multipoint alignment", otherwise known as image morphing. The basic idea is to do a normal align as best you can and then start distorting parts of the image to make it match up with your reference frame even better.
I'm still a ways off having it working properly, but I thought you might like to see the output of the software as it currently stands - there are many artifacts (the horizontal/vertical lines) which will go away when I implement more of the algorithm that I have so far. What I have so far is a very crude test implementation.
The thing to notice about this image is that it's equally sharp all the way across - the algorithm tries to get all of each frame to line up with the reference frame.
This is also just a stack of 220 frames, so it's a bit noisy. However when you compare it to the earlier Theophilus (in the other thread) remember that the other image is a stack of about 2000 frames using registax, and it gets blurry when you look closer to the edges.
hmm, it's after midnight, so.... Merry Christmas!
