I recently started using Hugin to create 360° panoramas of HDR images. The images I am trying to stitch together are in OpenEXR format.
I noticed that cpfind hardly finds any control points on these HDR images. If I convert the images to LDR first, then cpfind actually finds quite a few control points. I poked around in cpfind and found out that this is probably because the HDR images are first mapped to [0,255] before any features are detected. As this is done using a linear mapping the images end up being mostly black with only the brightest parts in the image visible. (Usually the sun...) When I switched the mapping in cpfind to logarithmic in the source code, the results became much better and more control points were found. Is this a known issue, or am I doing something wrong? I am using hugin on ubuntu 16.04 64bit. I built hugin myself from hg revision:674a88cfacb6468ac185c8e12392ba9c206a7113 -- Torsten -- 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.
