Re: 6 images (cube map) into equirectangular?

I have a similar, but "reverse" need: I'd like to get multiple images from a spherical image. Each of the multiple images should show what I'd see looking toward a specific direction in the sphere. But I don't know which projections are involved, any help?

Re: Fisheye 235° to equirectangular

SED converter is not working on my system (Win7), it complains about some "garbage" being present in cim.txt.
I'll try with manual conversion described in last example.

Re: Fisheye 235° to equirectangular

I'm studying "Generic Mapping Tools" (GMT), Flexify Plugin, NASA G.projector, Marzipano tool,... but still can't figure out how to get what I need. :-(

It looks interesting, but how can I run it in Windows?

Fisheye 235° to equirectangular

How can I convert a fisheye picture with FOV=235° into an equirectangular projection?

Can Imagemagick create a "paper globe"?

Would it be possible to instruct Imagemagick to build one of these projections starting from an equirectangular one? http://globemakers.com/paper_globes/Paper_bag.jpg http://astropedia.astrogeology.usgs.gov/download/Docs/Globes/mars_mola_globe.pdf/full.jpg I tested several programs, but I could only...

From spherical to planar image

I shot a photo to a metal ball reflecting surroundings.
How can I turn this photo into an equirectangular projection for viewing it with panorama viewers?
Photo was shot looking at the sphere from bottom upwards.

Project a disk to a plane...

I have this image:
http://photojournal.jpl.nasa.gov/jpeg/PIA19932.jpg

I want to convert it into mercator projection; of course it will be just half the width of a full mercator projection, as it's just one emisphere, but it's ok for me.

How do I do that?

Since I installed Nokia OVI Suite I can't run any java program, as .JAR is nowassociated to "installation on phone"! :(

Re: Jigsaw puzzle solver

It works in Win7 Pro for me. In a DOS window just use the command: siftwin32 <book.pgm >book.key Pete This is very weird: of course I tried this example, but I always got a PGM file inside the .key file, and the program output itself said "PGM file created" or something like that. Now I just tried....

Re: Object Recognition, what is possible and fast?

any news about this topic? I found a similar algorithm, SIFT, and a Windows port (siftWin32), but I can't get it working. http://www.cs.ubc.ca/~lowe/keypoints/ I also found another windows source... but I can't get it even compiled: http://nashruddin.com/template-matching-in-opencv-with-example.html...

Re: Jigsaw puzzle solver

Does ImageMagick have any SIFT/SURF feature/implementation?

I found this cool SW... but I can't get it working in windows (can't get the .key files)

Re: Jigsaw puzzle solver

There are many methods of comparing images. But for a jigsaw, I do not think just simply rotating the piece in 4 (90 degree) units will be enough. Can you be sure you actually get the 'piece' with exactly the right rotation? why not? As such you will need to look at a rotation invarient method of d...
