autopano-sift-c sourceforge tarball build instructions ?

[Barney Holmes]

Hi,

I wanted to try autopano-sift-c again as it was the first algorithm I discovered for matching images. I also had some bad performance from cpfind and wanted to compare with sift.

I followed this guide ...

http://mayukhmukherjee.wordpress.com/2014/04/05/installing-hugin-autopano-sift-c-in-linux/

But I always get a segmentation fault.

But I found "(Note February 2011: The latest source code of autopano-sift-C has been unstable for a long time now and nobody is working to fix it. Use the 2.5.1 release tarball instead)" - http://wiki.panotools.org/Hugin_Compiling_Ubuntu#Autopano-sift-C

However I can't see how to build the release tarball from sourceforge. There are no build instructions. I tried adapting the mercurial build instructions but it fails in being unable to find AutoPanoSift.h

Thanks for any help in advance.

Which linux distro are trying to build for?
If you are building for Fedora I can provide you with a .rpm for fedora
20, or a .src.rpm if you want to rebuild from that.
If it's any help, to build the rpm from the tarball I use cmake.
AutoPanoSift.h should be included in the tarball. If it isn't, sing out,
and I'll see if I can get a complete source to you.

Cheers,

 Hi Terry,

I'm using Debian but I think I can use the binaries in the fedora RPM, or failing that build the source rpm.

The AutoPanoSift.h *is* in the tarball. I think I'm starting cmake in wrong directory.

Thanks !

Ok, I managed to find the Fedora source RPM. I had to do a little fixing to make it build on my Debian 64bit system (see console output at end of message as well).

"/usr/bin/ld: warning: libjpeg.so.62, needed by may conflict with libjpeg.so.8" fixed by installing default "libjpeg-dev" which removed conflicting packages.

"undefined reference to symbol 'exp@@GLIBC_2.2.5'" fixed by adding "m" to following lines in CMakeLists.txt (adds explicit search for library) - "TARGET_LINK_LIBRARIES(generatekeys ${all_libs} m) ... TARGET_LINK_LIBRARIES(autopano ${all_libs} m)"

"autopano-sift-c" executes with no options to the point of showing its help message ...

autopano-sift-c: Find control points giving a Hugin project file

   Version 2.5.1 for hugin 0.7

autopano-sift-c [options] output.pto image1 image2 [..]
                hugin project file output.pto gets the results 
                input images can be jpeg, tiff, or other formats.

autopano-sift-c [options] output.pto projectfile
                projectfile: a hugin project or other PT compatible
                script with image file names, projections and angular
                widths.  Enables stereographic projection.

Options
  --ransac <on|off|1|0>   Switch RANSAC filtration on or off (default: off).
  --maxmatches <matches>  Output no more that this many control points per
                          image pair (default: 25, zero means unlimited)
  --maxdim <n>            Make largest image dimension <= n (default: 1600).
  --projection <n>,<d>    n = PT format code, d = hfov in degrees.  These
                          apply to all images, reprojection is enabled.
  --ANNmatch <on|off|1|0> Use fast keypoint matching tree (default: on).
  --disable-areafilter    Do not use max-area filtration, which is default.
                          See manpage for details.
  --integer-coordinates   Truncate match coordinates to integer numbers.
  --absolute-pathnames <on|off|1|0>   Use the absolute pathname of the image
                          file in the PTO output file. Disabled by default.

Alignment options
  --align                 Automatically pre-align images in PTO file.
  --bottom-is-left
  --bottom-is-right       Use in case the automatic algorithm fails.
  --generate-horizon <c>  Generate up to 'c' horizon lines.

Refinement options
  --refine                Refine the found control points using the
                          original images.
  --refine-by-middle      Use the best middle point to refine (default).
  --refine-by-mean        Use the mean of the patches control points.
  --keep-unrefinable <on|off|1|0>
                          Keep unrefinable matches (default: on).
output.pto: The output PTO panorama project file.
    The filename can be "-", then stdout is used
image<n>: input image files (any common format: JPEG, PNG, TIFF, ..)
Notice: for the aligning to work, the input images shall be
  1. All of the same dimension and scale
  2. The first images must be an ordered row. See manpage.

But giving anything else results in a segmentation fault.

It's the same with the Hugin sourceforge tarball download of the same code.

Can you get it to build and stay stable ? I am using Debian Testing. So there's possibility that there might be a bug in a library somewhere. I'll try building on another system when I get some time.

It builds OK and is stable here on Fedora 20.
The cmake messages look a bit suspect to me, but I am guessing.

I'm not sure if it will help you, but I have put my Fedora rpm and src.rpm
on Dropbox, here...

https://www.dropbox.com/sh/ix5nsjjsy5fprzu/AAAFTPCEPWuLxRr_qQoBH5s8a?dl=0

Looking at the date that I built the rpm (Jan 2014) I would have been
using libpano13-2.9.19.

Does this help...

[Barney Holmes]

Ah, got it.

I converted my PNG images to TIFF and now it no longer seg faults. Glad I remembered to try some simple tests first before delving into gdb which I'm not familiar with.

I'll put this in as a bug report.

Thanks for the help Tduell ! :)
