That is really an interesting technique!
I’ve written a small script that automates the whole procedure using PhotoFlow’s batch processor. For the moment it is just a test, so it is not yet very user friendly (and not really tested in detail…).
Assuming you have photoflow installed and you are under Linux (I still have to figure out how to do the same under Windows and OSX), all you need to do is to unpack the tar file in some folder of your choice, and copy the RAW files of the images to be averaged into the input sub-folder.
Then you can type
./superresolution.sh
and wait for the
output/averaged.tif
file to appear.
The script will develop each input RAW file (using some default parameters like CAMERA WB and sRGB output) and upscale it by 200%.
Then it will use align_image_stack to align each image (this command is part of the Hugin suite), and will generate an output/averaged.pfi file to load each aligned image and blend it with the previous ones at decreasing opacity.
Finally, the output/averaged.pfi file is saved into output/averaged.tif
If you are interested, I can give you more details on how it works and how it can be tweaked (for example, how to change the RAW development settings).
