[hugin-ptx] Documentation on align_image_stack
Hello everyone, Working in an hydraulic lab, I've been using align_image_stack for a project aiming at measuring rivers discharge from images. Align_image_stack give me great results, now I would like to understand how it works. So I was wondering if someone could tell me in few words what is the process used by align_image_stack to find control points ? I've been looking for documentation on this but couldn't find anything...

I've been looking for documentation on this but couldn't find anything... It matches a pair of images at a time. For the first image it locates a set of 'corner features' using a grid to try and spread them over the whole image, corners are useful because they look the same under different magnifications, but have two dimensional detail. For each point it tries to find the equivalent feature in the other image by comparing small patches of pixels and shifting them around - This is the same process as the Hugin 'fine tune points' function, but it only works if the images are nearly aligned in the first place. The rest is the same as a normal Hugin alignment optimisation using these features as 'control points'. -- Bruno -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups hugin and other free panoramic software group.

Re: [hugin-ptx] html page title
I just changed it. There is something entirely wrong with sourceforge's publishing mechanism. I already made more changes and only yesterday I found out that you have to update both the default branch of hugin-web as well as the htdocs branch of hugin-web. I hadn't seen the (stupid) mistake in the release notes, but I just adapted it as well in the htdocs branch. I assume it will be up-to-date in 1-2 hours.

Re: [hugin-ptx] Strange output from Hugin-2013.0.0
Am Mittwoch, 13. November 2013 um 23:21:30, schrieb Neil nsheph...@gmail.com Hi, Running Hugin-2013.0.0 under Gentoo (built 29th October 2013 from source) and since this update I've been unable to create panoramas. Control points are created, but in the preview only one picture is shown, regardless of toggling which ones are displayed. Feels, like you did not optimize (after creating the control points) When I then Stitch the resulting output is just one of the files in the projection required for it to be stitched, no other files and no resulting image where they are merged and cropped. No idea how to go about trouble-shooting this nor what information might be required to help (please let me know if I should provide some information).
