Add Buy Online Url Viagra

August 4, 05

Add buy online url viagra Hugin iconHugin is a cross-platform GUI that allows the user to “assemble a mosiac of photographs into a complete immersive panorama, add buy online url 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, add buy online url viagra Hugin seemed like the perfect tool for me.

Add buy online url viagra I went to the Hugin for OSX port page, add buy online url viagra navigated to the download section, add buy online url viagra and grabbed a copy. Add buy online url viagra After downloading, add buy online url viagra I quickly realized that like most open source programs, add buy online url viagra the documentation on how to use Hugin was sorely lacking. Add buy online url 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.

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

Add buy online url viagra After installing Mono, add buy online url viagra I noticed the following line in Hugin’s explanation on how to get Autopano working:

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

Add buy online url viagra As usually happens, add buy online url viagra the very easy way did not work for me, add buy online url viagra so I had to do some minor shell script editing. Add buy online url 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, add buy online url viagra I thought I was ready to rock.

Add buy online url viagra However, add buy online url viagra Hugin quickly let me know that my rocking was yet to happen. Add buy online url viagra Instead, add buy online url viagra it gave me this error:

Error message from HuginOSX

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

Add buy online url viagra Eventually, add buy online url viagra I realized that Autopano does not like it when the images you’ve added to Hugin have spaces in their path or filename. Add buy online url 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”), add buy online url viagra my images were analyzed and properly linked.

Add buy online url 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. Add buy online url viagra But with the little experience that I do have, add buy online url viagra I was able to successfully turn thirteen separate images into this:

Pano after Hugin and Autopano stiched it up

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

Add buy online url viagra Once this is complete, add buy online url viagra you can run the images through Enblend via the command line in Terminal. Add buy online url 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

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

Add buy online url viagra Enblend looks at the various parts of the TIFF files that overlap, add buy online url viagra and figures out how to blend them. Add buy online url 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.

Add buy online url viagra If you compare the image below to the image above, add buy online url viagra you’ll see how great a job enblend does:

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

Add buy online url viagra My biggest gripe with the Hugin is its lack of documentation. Add buy online url viagra There are numerous options and optimization modes that are not referenced anywhere in the help. Add buy online url viagra Sure, add buy online url viagra I can look around online for most of the information, add buy online url 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.

Add buy online url viagra That’s not to say Hugin and its associated tools are bad, add buy online url 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. Add buy online url viagra

Add buy online url 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

    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.
