Reinventing ourselves since 2001


Cheapest Viagra

August 4, 05

Cheapest viagra Hugin iconHugin is a cross-platform GUI that allows the user to “assemble a mosiac of photographs into a complete immersive panorama, cheapest viagra stitch any series of overlapping pictures and much more.” Having long wanted to create panoramas but lacking the skills and time to make one that looks good, cheapest viagra Hugin seemed like the perfect tool for me.

Cheapest viagra I went to the Hugin for OSX port page, cheapest viagra navigated to the download section, cheapest viagra and grabbed a copy. Cheapest viagra After downloading, cheapest viagra I quickly realized that like most open source programs, cheapest viagra the documentation on how to use Hugin was sorely lacking. Cheapest viagra I eventually learned how to do what I wanted to do through trial and error as well as reading numerous tutorials scattered around the web.

Cheapest viagra My first headache was getting Autopano to work, cheapest viagra which is arguably the most important tool that Hugin can use. Cheapest viagra When it works, cheapest viagra Autopano scans through the images you add to Hugin, cheapest viagra finds where they overlap, cheapest viagra and figures out the best way to stitch the images together. Cheapest viagra The version of Autopano linked within Hugin’s tools folder requires that the Mono environment be installed on your computer to work, cheapest viagra so pick that up first.

Cheapest viagra After installing Mono, cheapest viagra I noticed the following line in Hugin’s explanation on how to get Autopano working:

Cheapest viagra There are two ways of using Autopano-SIFT from HuginOSX. Cheapest viagra One is very easy, cheapest viagra but does not always work, cheapest viagra and hence not supported. Cheapest viagra The other should work as long as you set up autopano-sift correctly, cheapest viagra but it involves editing shell script.

Cheapest viagra As usually happens, cheapest viagra the very easy way did not work for me, cheapest viagra so I had to do some minor shell script editing. Cheapest viagra After following the instructions and properly setting up the AUTOPANO_PATH variable and changing every instance of “generatekeys.exe” to “generatekeys-sd.exe” in the autopano-complete.sh file, cheapest viagra I thought I was ready to rock.

Cheapest viagra However, cheapest viagra Hugin quickly let me know that my rocking was yet to happen. Cheapest viagra Instead, cheapest viagra it gave me this error:

Error message from HuginOSX

Cheapest viagra I double, cheapest viagra triple, cheapest viagra and quadruple checked my changes to the shell script, cheapest viagra and I couldn’t find what I’d done wrong. Cheapest viagra I completely removed Autopano from my computer and downloaded a new copy to insure I hadn’t inadvertently changed something else.

Cheapest viagra Eventually, cheapest viagra I realized that Autopano does not like it when the images you’ve added to Hugin have spaces in their path or filename. Cheapest viagra So after changing the folder and file names (in the example case seen in the error message above from “folder with spaces” to “folder”), cheapest viagra my images were analyzed and properly linked.

Cheapest viagra I’m not going to go into the finer points of optimizing the panorama by adding vertical and horizontal lines or any other such thing - I do not have the experience or knowledge of Hugin to be considered a source on such things. Cheapest viagra But with the little experience that I do have, cheapest viagra I was able to successfully turn thirteen separate images into this:

Pano after Hugin and Autopano stiched it up

Cheapest viagra If you click on the image to see a larger version, cheapest viagra you’ll see that the stitching areas between images are very visible, cheapest viagra and very ugly. Cheapest viagra This is where Enblend comes in. Cheapest viagra Although Enblend can be run from within Hugin by selecting the “into a high quality TIFF file” option in Quick Stitcher, cheapest viagra I recommend against it. Cheapest viagra Instead, cheapest viagra export everything as multiple TIFF files.

Cheapest viagra Once this is complete, cheapest viagra you can run the images through Enblend via the command line in Terminal. Cheapest viagra An example command would be:

/Applications/HuginOSX/tools/enblend/enblend -v -o \\
/Path/To/Save/Final/Pano/Image.tiff \\
/Path/To/Image/1.tiff \\
/Path/To/Image/2.tiff \\
/And/So/On.tiff

Cheapest viagra Enblend takes quite a while (can be many hours depending on image size, cheapest viagra number of images, cheapest viagra and processor speed) to do it’s stuff, cheapest viagra and I prefer running it through the terminal so I can free up system resources by closing Hugin. Cheapest viagra There isn’t any sort of progress indicator or time remaining information in enblend, cheapest viagra so I run it with the -v flag (verbose) to keep me from thinking my computer froze.

Cheapest viagra Enblend looks at the various parts of the TIFF files that overlap, cheapest viagra and figures out how to blend them. Cheapest viagra It will blend images over a wide area in parts of the images where there is little variation in the surrounding area - like in skies and clouds - and will blend images in a very small area where people won’t notice a harsh transition - like in rocky areas or in tree trunks.

Cheapest viagra If you compare the image below to the image above, cheapest viagra you’ll see how great a job enblend does:

Cheapest viagra For the next step, cheapest viagra I played around with enblend’s exported TIFF image in Photoshop. Cheapest viagra I used the Stamp tool and Gaussian blur filter almost exclusively, cheapest viagra and am pretty happy with the results. Cheapest viagra There are some areas I could spend more time in, cheapest viagra like making the sky areas that I added look more uniform, cheapest viagra but overall I think it looks pretty good for a first try.

Cheapest viagra My biggest gripe with the Hugin is its lack of documentation. Cheapest viagra There are numerous options and optimization modes that are not referenced anywhere in the help. Cheapest viagra Sure, cheapest viagra I can look around online for most of the information, cheapest viagra but it would save every new user a half-day’s worth of time if all of that information was put in the one place it should be - Hugin’s help file.

Cheapest viagra That’s not to say Hugin and its associated tools are bad, cheapest viagra because they aren’t - they just lack the information necessary for new users to get up to speed in a short amount of time. Cheapest viagra

Cheapest viagra Some statistics from the project:

  • Total pictures stitched: 13
  • Final resolution of panorama: 17964 x 2529 pixels.
  • Total time necessary for me to be at computer: ~30 mins.
  • Total time my computer spent on processing the images: ~6 hours

Cheapest viagra In case you’re curious, cheapest viagra the panorama shows what you can see from the top of Mt. Cheapest viagra Rose, cheapest viagra the third highest peak in the Lake Tahoe Sierra. Cheapest viagra You can see some other pictures from the hike here.

    I was having the same problem with spaces and couldn’t figure out what was going wrong. Thanks for clearing it up!

    You really could have just used photostitch 3.1. It came in the box with your camera and requires about 3 clicks and a hair under 6 hours to stitch pictures.
