[hugin-ptx] Re: Remapped images and bracketed exposures
Just to close this topic, I've submitted a feature request (#2939561) to support this capability inside Hugin (no standalone tools required). Text follows. Rick The Problem: Small stitcher errors caused by nodal point errors, poor choice of control points, and/or motion can often be corrected in Photoshop using layers and masks if the exposure corrected, remapped source images are available. For Normal output, these are kept if the Remapped images option is enabled. However, for Exposure fusion:Fused and blended panorama, the Remapped images option only keeps the uncorrected remapped images, i.e., the input to the enfuse process. The corrected images (i.e., projectName_stack_ldr_N files ) are designated temporary and erased when the blending process is complete. This precludes fixing the seam errors in Photoshop. WorkAround: The desired files are actually produced as part of the stitching process. Using a standalone copy of the Hugin_tools (I got mine from Harry van der Wolf's website), the project file can be run through a pto2mk and make all process to generate the desired files. (I created a scriptlet that you can drag and drop a project file on to automate this process.) Any unnecessary temporary files must then be removed manually. The disadvantages of the workaround are obvious: additional manual steps and downloading of the standalone tools which wouldn't otherwise be necessary. Feature Request: Add support to the GUI stitcher tab so that the projectName_stack_ldr_N files are retained. Some possibilities: a) Add additional Exposure fusion checkbox to retain exposure corrected, remapped images when Fused and blended panorama is selected. b) Extend semantics of current Exposure fusion:Remapped images checkbox to also save projectName_stack_ldr_N files when Fused and blended panorama is selected. c) Use Normal:Remapped Images checkbox to enable saving of projectName_stack_ldr_N files when Exposure fusion:Fused and blended panorama is selected. (This is my least favourite option due to potential user confusion and should probably only be done in the context of a redesign of the Output GUI.)

I've installed Hugin_tools from Harry's web site so I can run pto2mk on the project file and then run make on the result as suggested. Not particularly user friendly but I'll try and put a wrapper around it to make it easier. I'd still like to see this supported through the GUI somehow, but this will work for now.

If you stitch on the command-line with 'make', nothing is deleted: make -f project.pto.mk all Running 'make clean' will then delete all intermediate files: make -f project.pto.mk clean Can you point me at what I need, in addition to the Hugin Mac binary I have have already installed? Also is there any doc/tutorial that will tell me how to do this? My terminal skills are a bit rusty.

Maybe I'm not communicating this well, but they appear to exist temporarily as *_stack_ldr_* files, e.g., test_stack_ldr_.tiff, during the process, but the cleanup throws them away. So I'd just like an option (or parameter setting) that doesn't delete them. This is consistent with my understanding, i.e., Fused and blended panorama exposure fuses the bracketed stacks into one set of images that are then blended just like a single set (non-stacked) of images.

An exposure-corrected, exposure-fused image doesn't really exist, adjusting exposure before fusing doesn't improve the results. Actually, both options appear to produce the same set of remapped images. They will produce similar images if Hugin thinks they all have the same EV. If Hugin can't read the EV from the EXIF data, you will have to run exposure optimisation. Sorry if that sounds complex, what you are trying to achieve will probably work, but it isn't a typical workflow. -- Bruno -- You received this message because you are subscribed to the Google Groups hugin and other free panoramic software group.

[hugin-ptx] Remapped images and bracketed exposures
I know this topic has been generally discussed in this group, but I couldn't find an answer to my specific question. Using the GUI, when I output a Blended panorama with remapped images I get the equilateral and a set of remapped and exposure corrected images. Using Photoshop layers and masking, I can use them to patch up minor stitching errors, since the individual images have the same exposure correction as the main panorama. However, when I have a bracketed exposure set of images and output a Fused and blended panorama with Remapped images, the remapped images do not have exposure correction applied. They appear to be the remapped original exposure images prior to fusing, and therefore aren't much help in the patching process. Is there any way to retain (I'm sure they're being generated) the set of exposure corrected images (like the set for Blended panorama) produced just before the final output?

[hugin-ptx] Re: Remapped images and bracketed exposures
I have tried that option (and a few others) but it produces remapped but uncorrected versions of the original 18 images, rather than a set of 6 corrected fused images. I'm using Harry van der Wolf's recent build (2010.1.0, svn level 4892).

Not sure I understand. I choose Fused and Blended panorama as output. Now whether I select Normal:Remapped images or Exposure fusion:Remapped images I get remapped versions of the 18 images prior to fusing, rather than 6, exposure corrected, fused images, which is what I'm looking for. Actually, both options appear to produce the same set of remapped images. Based on the tooltip for Exposure fusion:Remapped images, I'm getting the expected result for that option. It would be nice if Normal:Remapped images produced the desired result, but it doesn't appear to do so. Am I missing something?

This should work, though you can always stitch everything twice, saving 'remapped images' for both 'Normal' and 'Exposure fused' output. -- Bruno -- You received this message because you are subscribed to the Google Groups hugin and other free panoramic software group.

[hugin-ptx] Re: Control Point Detectors on hugin-mac-2009.2
Hi Harry, Thanks for the update. I've never found the auto control point generators particularly useful for fisheye images, but the align_image_stack would help quite a bit setting up stacks of bracketed exposures for HDR, so I'm keen to give it a try. Please let me know when something becomes available. Rick On Dec 16, 1:59 pm, Harry van der Wolf hvdw...@gmail.com wrote: Hi Rick, I had a look at it, but currently it is harder than it seemed: - I tried to implement it from inside the bundle, but I did not get that to work since the switch to the new 2009.x plugin structure. - I tried to make it as a align_image_stack plugin for Hugin. The big problem lately is that I can't make a static align_image_stack anymore. I get segfaults when building. (This is the same for the other hugin command line tools.) And then came other things in sight. All in all I'm not much further. I will have a look again this weekend.
