Hi, Jeff!

Sorry to have missed your comment!

This was produced simply with ordinary orbits for the most part. All shots in this synth are original resolution - no cropping involved.

Although cropping a photo into bite sized pieces does allow the synther to find more image features, I find having all the crops in the synth really unsatisfactory for photo viewing purposes.

Deep Wood House: Greenhouse

Sat, 18 Sep 2010 13:27:27 Z

"It had been far too long since I was able to go and shoot a good honest synth so I headed over to our town's largest park with the thought of shooting a historic house, but remembered this greenhouse when I got there and didn't get any farther as I've been wanting to shoot a greenhouse and plant nursery for quite some time. Sadly my battery packs both died before I quite finished shooting the detail that I would have liked due to my need to shoot with my flash nearly the entire shoot but in all honesty I don't know how many more photos I would really be able to fit into this one synth. That said, it was very therapeutic to see a respectably sized new pointcloud form from my photos."

Hey, thanks!

Here are a couple of other cactus related synths that I have admired in the past:

Wou! Nice! I see - you are an expert in panoram's projects. and i have some problems with it. The ICE doesn't want to publish.. could you help me? You can find on Windows Live.

Nice 360 pano.

OHS: 1296 Tiles Alone

Sun, 28 Feb 2010 02:54:41 Z

"As detailed elsewhere, I have long been interested in allowing the synther to examine every last pixel of my photos for image features to match, rather than only the image features able to be found in 1.5 or 2 Megapixel versions of the photos, as it has done since its launch. I knew that if I chopped the original resolution into pieces smaller than the 1.5 Megapixel limit, that Photosynth would not resize these pieces. I did, however, doubt whether Photosynth was clever enough to place the tiles of the original photos accurately enough to make each original image appear seamless when slightly zoomed out from any given tile, so had planned to include both the pieces of each image (to get every detail examined) along with the actual original images (to provide the synther with a confirmation of how close the tiles were to each other and to actually look at), even though the originals would only be matched based on their 1.5 megapixel versions. Since all 130 original photos had been calculated to be 100% synthy before, I knew that the tiles had an excellent chance of matching, but I also knew that parts of some of the images like the background behind the hydrant that was out of focus (because of the shallow field of view) which contained no texture to match might fall out of the synth if I synthed the tiles alone, but might match their parent images if I could include both. In the end I tried on two separate weekends to make a synth containing the 130 originals as well as square tiles of exactly half the width of my portrait photos or half the height of my landscape shots (these tiles are still not quite smaller than 1.5 megapixels, but still allow the synther to look at objects more closely than the small versions of the original images). Each time, this combination of these particular photos and their pieces threw my iMac's dual processors into a furious 50+ hour battle which ended in an out of memory error. Finally, I decided to simply try making a synth with only the pieces of the originals, leaving the whole original images completely out of the picture. True, there would be some tiles that would not have anything to match due to being out of focus background and the alignment of the pieces of the original images wouldn't fit together perfectly, but this experiment was really more for the pointcloud anyway. It is, in fact, far more dense than the pointcloud calculated from the original images alone, as I had long ago predicted, however I wish that I had a way to align the pieces more perfectly. In the end, the Photosynth team has plans to enable us to resynth our photos at their full resolution which will do away with all of this nonsense of manually creating tiles of the photos just to get a denser point cloud, which will also leave the photos unmolested in the process, but this is one way for anyone who just wants to generate a dense point cloud for meshing to do so in the interim."

I hope you laught :-) You use very well photosynth. And i like your experiment, and more classical too.

Salem Capitol Lobby (Very Rough Draft)

Sat, 27 Feb 2010 06:57:32 Z

"This was mainly a bit of field research to see how many photos I should expect to dedicate to different parts of the building in order to come out to a satisfactory degree. As with many of my tests, it was shot fast and sloppy. The white balance is way off, shots aren't level, shots are blurry from moving the camera when shooting, shots are horribly framed, etc. etc. I'm encouraged, overall. I'll have to be more patient next time, obviously, but I wasn't sure that the majority of this was going to hang together. The parts that disintegrated are largely the fault of blur or of me cutting corners in my coverage where I shouldn't have. The geometry is very simple here, but the complication is that everything is very shiny and very big. I'd like to integrate the front and back doors as well as the rest of the first floor, but I'm going to have to be very disciplined in which shots I choose because I have yet to see a synth succeed with 2000 or more good clear photos as input."

This is amazing! Overhead view is fantastic!
Good work! thx

Geology Case (Incomplete)

Fri, 26 Feb 2010 22:14:21 Z

"I had to abort my shoot of this case (so far I've only shot perhaps a third of it) because my flat battery pack suddenly decided to refuse to eject so that I could replace it with my charged pack. I'll be back to finish this... eventually. I make no promises as to when, though."

Incomplete, i don't know why ! Very nice.

One last note: if you're keen on pointclouds of natural objects, check out my Orbital Propulsion (Gravity Assist) synth here:
http://photosynth.net/view.aspx?cid=5f415186-f783-43a2-bd5f-92aa3a9603df

I had been kicking around the theory that shooting orbits as the primary pattern of photography would most efficiently yield the greatest returns in terms of pointcloud reconstruction for some time at that point but had yet to make myself actually walk outside and find something worthy to shoot.

The results that morning were most definitely a turning point for me and, although I was not nearly methodical enough in my circling of each bloom, it hung together. The results of taking my time and using a tripod to shoot would, I think, greatly increase the clarity of each flower. The stems are another problem altogether, simply because they are so small, but it's probably one of my biggest pointclouds.

Deep Wood House's South Lawn (Odds Half)

Wed, 23 Sep 2009 17:15:05 Z

"This is part of one of my synths that I've been trying to make work since the 8th of September. It's only a small portion of the grounds around the Deep Wood House in Salem Oregon's Bush's Pasture Park but it's a beginning. Photosynth keeps running out of memory while analysing the full set of photos because they are all of things which generate a lot of 'image features' (the patches of texture in your photos that Photosynth matches to figure out how the camera positions and points in the photos match and relate to each other). After trying fewer and fewer photos at one time, being forced down near to half the number of images, and becoming more and more irritated that objects featured in both earlier and later photos would not get the extra detail in the point cloud that they should if all the photos were together, I thought that if I had to make a synth with only half the photos, I would at least choose photos that were evenly spaced from the beginning to the end of my photo set. I've now successfully synthed (97% 'successful' anyway - some annoying rifts were introduced in the point cloud because of missing every other photo in these 'half' sets) both the odd numbered photos and the even numbered photos as separate groups. Someone who had viewed one of the synths and later found the second might mistake it for the first one that they had seen and comparing the point clouds of both show that they are truly very similar but the detail and density of the point cloud that is lost because of missing the matching that should happen between the evens and the odds is very unfortunate."

I'm honoured to make the cut, Jim.

If any of your kids has an iPhone, you should download the free iSynth Photosynth viewer for it. If you get the chance, check out Orbit Mode, as it adds a little twist on viewing synths you already know well.

The free Seadragon Mobile app is also very cool as an image browser. It's not at all 3D and there's no point cloud, but it does much better on zooming down to the last detail of every image in a synth. Although iSynth is cool, it doesn't do such a great job of letting you zoom all the way in on an image. Put the two together, though, and you have the entire experience.

Just a little sip...

"This is a little blind kitten that lives just next door that I've been able to tame. This was the first time that I'd ever seen her drink from the water that the other cats drink from and considering the hydrophobia that she has I was somewhat surprised at how she didn't shy away from the tub when her paws got damp from resting them on the edge."

Nathanael Over 1 year ago

Muchas gracias, mio amico. =) This is one of my favourite small synths. I've tried my hand at larger ones as well, if you'd like to take a look.

Sadly this little creature disappeared on November 20 2009, almost exactly two weeks after this synth was made. It rained long and hard that afternoon and evening but she never met me to be fed. I went walking up and down all the streets around my part of town several nights and afternoons over the next week calling and looking for her body in case she had been hit by a car, but I never saw another trace of her.
