Yet another non-rigid registration and stacking tool.
This time using the “demons” technique for non-rigid registration (matching) of AVI frames.
I hope the enforced workflow makes the use of the software clear by itself:
download: RegistaC# (2328)
.NET 2.0 required if not already installed
The application was entirely written in C# (VS2005 express), making use of the FFTW library for FFT (wavelet filtering and global shift detection) and the AVI library from Codeproject.
The idea is
1. open avi and select a nice frame
2. align all other frames to that frame
3. measure quality of all aligned frames in preferred region of interest
3. average best X% frames
4. correct all sharp frames for seeing using “demons”
5. stack again for final result
6. apply wavelet sharpening
after that you can re-iterate alignment, seeing correction, frame selection etc. quite ad-lib.
Here is an explanation of the demons technique: demons powerpoint
feedback more than welcome!
