Pattern recognition and stitching images to reconstruct a panorama

H,
I am taking around two hundreds snapshots of an object of 1m long and I would like to recreate a full panoramic image.
I can basically do it manually (it works fine) by imposing a identical offset in between all pictures but sometimes a small delay in the image acquisition is perturbing the assembly.
Therefore, I would prefer to use an algorithm to do it automatically and find the best offset for each snapshot.
I have seen that a development already exists although this is far to powerfull for my application (http://zone.ni.com/devzone/cda/epd/p/id/6497). However, it is developped for Labview 2010 and I have only LV2009. I do have Vision 2010.
Could anyone comment on this and let me know if it would be adapted to my needs?
If so, could anyone convert that vi's in 2009 format or provide something equivalent?
Thanking you in advance.
Cris.

I don't have LV 2009, but I've saved it back so hopefully it works for you. Looks like a nice solution - whether it will work will probably depend on the content of your images, and whether there are distinct objects to match up. I've had a similar problem in the past, but rather than finding particles, I've computed a cross-correlation as the measure of where to overlap images. You could probably adapt this code to use a different alignment technique.

Stitching images of the sky and the ground

I know how to create a panoramic shot using several images taken side by side. My question is, can you create an up and down panoramic image of say, the sky and then the ground. Example: I take a picture of a beautiful sunset and then take a picture of the ground right below the sunset to show the two images combined to show an up and down panoramic shot of the effect of the sunset is having on the ground below it. Is this at all possible?

A vertical panorama? Well you can make multi row panoramas, so there is no reason that you couldn't stitch a single column. An excellent example (set of examples to be more accurate) are Herman Klaus's Vectoramas, which are taken with a hand held camera, merged to HDR in Photomatix, and stitched in Photoshop
Herman (aka Farbspiel) has an excellent site about HDR
http://farbspiel-photo.com/
And if you follow the Learn link on his page, there are some of the best step by step guides I've ever seen. The videos are an even better source of information, and demonstrate just how much work goes into making an image look like the one above

Real time pattern recognition

I'm trying to build a pattern recognition system, so that I can detect in real time "STOP" traffic signs. I've build a template and a script using Vision Assistant, an then I used the "Export to VI" option. I've been trying to modify the generated VI, to add the webcam part. I can't figure out what's wrong, as the program captures video, but the pattern recognition part doesn't behave as I want,it just applies some image filters and displays the first captured image. I'm a begginer in LabVIEW, please help me figuring out what's wrong. It should show the captured video, marking the pattern if one is found. Thanks

Hi Nathan,
Thanks for the reply. I've managed to solve some of the issues. I've given up trying to do the geometric matching real time. I just want to do this against a couple of local images. My big problem right now is that I can't manage to display the overlay over the initial image, as this gets distorted in the process (applying the color threshold, the equalize feature and so on). I guess I don't understand correctly how the matching algorithms work. I would greatly appreciate if you could point me in the right direction...basically, I want to display a rectangle overlay over the initial image. I have a couple of questions from there on, but I want this solved first. I've attached my latest VI, the VisionAssistant script for detecting the signs and an image I use to test. Thank you

Stitching images with overlays

I am stitching one large imaq image from several smaller images using image to image copy. The small images each have several overlays. After the image to image copy the overlays from the small images are lost. How can this be avoided. Or at least how can I get the overlay image information to manipulate it and reapply the data.
Is this possible, it seems that it should be.

The image overlay data is lost when performing the image to image copy because you lose the origin (0,0) of the small image, to which all overlays are relative.
You are going to need to user the IMAQ set overlay properties VI to configure the behaviors of the overlays before you copy them.
An easier method would be to merge the overlay with the picture before copy, but you would lose pixel data under the overlay, and the image would convert to RGB.

Perspective and stitching

So I'm playing with stitching to allow images wider than my widest lens would take and to capture greater resolution for larger prints. I'm playing with stitchings for 8-20 images. I've been using File>Automate>Photomerge... I've played with the various options and have found that merging with the "Auto" option, though the effect I want is the "Perspective" optoin.
Since the images to each side are with the the sensor plane angled away from the subject there is noticable perspective to both sides of the merged image. What I'm wondering is what the best type of correction to make is. The standard perspective controls are like tilting the back of a large format camera and only correct in one direction. I'm looking for something that might be like folding the perspective in the middle of the image.

In some cases my angle of view does exceed 120. In the image above the filed of view of the original captures is right at 180 degrees. But wierd things are happening in this picture. Note the logs on the left side of the image and the trees on the right side. A straight road runs along the edge of this scene and passes within five feet of both the logs and the trees. Outlet of this spring is that trail of brown and it is parallel to the road. The line of trees looks fine, but that is because the clearing is a semicircle, so the line of trees is relatively parallel to the sensor plane in each capture.
If I had an extreme shift lens, that would make better captures too, as sensor plane would remain parallel to the subject. Large format photographers and those familiar with tilt/shift lenses will understand. For an explanation of what's happening see: http://en.wikipedia.org/wiki/Perspective_control_lens
The reason the normal perspective controls in PS don't work quite right is that they assume one capture. Thus the correction is basically applying a trapazoid to correct that fact that the one capture had the sensor (film) plane out of parallel with the subject. In the case of a stitched image, the sensor plane is at multiple angles to the subject, and also in opposite directions from each other.

In IMovie my project view is fine until it is finalized and then images are getting partially cut off on top(people's heads etc) Is there something I can do?

My issue turned out possibly being a larger problem.
All of a sudden the server is in a bad, bad way. 30 minutes to get booted to the login screen. If I try to login I get beachballs for half a second at a time. I type login/password, the screen refreshes and I'm back to the login screen. I can't connect a keyboard/mouse directly to it, because it wants to do the keyboard recognition (I'm not using an Apple keyboard because they're all Bluetooth and I can't get in to do the Bluetooth sync). I can't do Disk Utility, because I can't connect a keyboard to do the key shortcut. I can't do Hardware Test, because I can't connect a keyboard to do the key shortcut. Can't reinstall Snow Leopard Server, because in their infinite wisdom Apple has removed the optical drive, and even if I had the optical, it wouldn't do any good because I can't connect a keyboard to do the key shortcut that would allow me to boot from the DVD.
I tried to do target disk override from Remote Desktop but it won't let me choose my other Mac's Remote Disc as a boot option. It also continues to show the Server as "Offline" even though power is on and it's on the network.
I would do my 2010 Air's USB drive - just to do a Disk Utility and see if it's a drive problem - but I can't tell the Server to boot from the USB stick.
Tried using my iMac as a monitor, that worked for a while, now it just flashes and then goes back to the iMac.
I'm thinking the logic board on this thing is about to die. Which is unfortunate, since my company opted out of AppleCare for this piece of equipment, and the 1 year expired last month. So...if the repair is going to end up being $800, they're going to have to pony up for a new server.

ACR and Stitching From RAW Files

I see something peculiar happening on recent stitches.
I have say, three frames to stitch from RAW. One frames a little overexposed, so I open in ACR, drop the exposure to compensate and save. Then I open all three frames in Photoshop>Merge as RAW files. When the adjusted frame shows up, the adjustment is ignored.
I can fix this by opening the other two and do a very slight change to them, save, then all three show up as expected, the bright one matching the other two close enough to get a uniform stitch.
Now I am doing this as a quick test of the stitch, to see if I really am interested, and if so, I go back and open all three in ACR and make the corrections. After doing all three, I can uncouple the bright one and tweak its exposure, then save and stitch, no problem.
Is this normal?

I am selecting the images after making the raw adjustments in Bridge and selecting Photomerge under the Tools.
I haven't experienced this either until now. The difference is that Iwould always select the images and open in ACR first, and run the corrections synchronized. Occasionally, one would be off enough to require special tweaking so after the synch corrections, I would select it, correct it then click Done. Getting a bit lazy, especially with many panos waiting, I do a quick test and in this case, only one of the three needed tweaking. Running Merge as above ignored the tweak.
Try it yourself. Pick some images to merge that have not been through RAW, and tweak one only in ACR. Click Done then Photomerge from Bridge under Tools.
I've done this twice now, after exiting Bridge and Photoshop first.
Make that three times

Automatic Pattern creation from Input Image

Hi all,
I've created a program to automatically create a patterns from an input image
1. The user selects image
2. with a rectangle he selects a zone of that image
3. An automatic pattern image is created as result of repeating that rectangle
It's working most of the times but sometimes:
1. The red rectangle which I use to select the area I want to repeat is not displayed
2. The area is not correctly handled and strange blank areas appear
Do you know how to solve these issues?
I put you here the whole source code so you can execute it and have fun creating patterns!

Part 2*
Now, about your red rectangle
class Selector extends MouseInputAdapter
    ImageSelectionPanel selectionPanel;
    Point start;
    Point end;
    boolean dragging, isClipSet;
    public Selector(ImageSelectionPanel isp)
        selectionPanel = isp;
        dragging = false;
        isClipSet = false;
    public void mousePressed(MouseEvent e)
        if(isClipSet)             // clear existing clip
            selectionPanel.setClipFrame(start, start);
            isClipSet = false;
        else                      // or start new clip
            start = e.getPoint();
            dragging = true;
            isClipSet = true;
    public void mouseReleased(MouseEvent e)
        dragging = false;
        end = e.getPoint();
        System.out.println("START="+start);
        System.out.println("END="+end);
        int width=(int) (end.getX()-start.getX()) ;
        int height=(int) (end.getY() - start.getY());
        if ((width>0) && (height>0))
        MergeImages.GenerateFourImagesDragAndDrop(crop1.fileName, start.getX(), start.getY(),width ,height );
    public void mouseDragged(MouseEvent e)
        if(dragging)
            selectionPanel.setClipFrame(start, e.getPoint());
}The problem stems from the isClipSet and dragging variables. I have no idea what you were trying to achieve with these. I'm guessing you're making certain assumptions about the way mouse events are received that are just plain wrong. Also, the logic in the MouseReleased method is wrong. The point you define as "start" is not necessarily the top left of the clip rectangle as you have it set up. But in this call
MergeImages.GenerateFourImagesDragAndDrop(crop1.fileName, start.getX(), start.getY(),width ,height );you're assuming it is the top left point. I imagine this might contribute to your "blank areas" issue, but I'm not sure.
Change your Selector class to the code below, and the rectangle will always work (at least it does on my machine --> java 1.6.0+)
class Selector extends MouseInputAdapter
    ImageSelectionPanel selectionPanel;
    Point start;
    public Selector(ImageSelectionPanel isp)
        selectionPanel = isp;
    public void mousePressed(MouseEvent e)
        start = e.getPoint();
        selectionPanel.setClipFrame(start, start);
    public void mouseReleased(MouseEvent e)
        Point end = e.getPoint();
        end.x = Math.min(Math.max(end.x,0),selectionPanel.image.getWidth());
        end.y = Math.min(Math.max(end.y,0),selectionPanel.image.getHeight());
        selectionPanel.setClipFrame(start, end);
        System.out.println("START="+start);
        System.out.println("END="+end);
        Rectangle clip = selectionPanel.clip;
        if(clip.width > 0 && clip.height > 0)
        MergeImages.GenerateFourImagesDragAndDrop(crop1.fileName,
                                                  clip.x,clip.y,
                                                  clip.width,clip.height );
    public void mouseDragged(MouseEvent e)
        selectionPanel.setClipFrame(start, e.getPoint());
}You will see that a new problem surfaces. That problem is that generated patterns affect previous ones. I imagine this has to do with your extensive use of static variables. Any swing person will tell you that a static GUI component constitutes as a bad idea in the majority of situations. But I'll let you deal with that.

Shading pattern bug with stitching functions

I am using Acrobat Professional 7 for Windows, but I don't believe the situation has changed in Acrobat 9.
I have a simple hand-crafted pdf that is designed to test shading patterns with extend regions when used with stitching (Type 3) functions. These behave according to the spec in most cases, but there is a special case where they don't. I've included the job at the end of this message.
The special case is where a Bounds entry is identical to one of the Domain values. The spec doesn't say what should happen for this case, but I might expect either the end child function would be ignored, or that it is used but the appropriate colour would be evaluated using it and applied to the extend region.
What in fact happens, is that the extend regions have their colour derived from evaluating 0 or 1 through the end child functions. This is true regardless of whether the shading domain includes zero. But, these are used the wrong way round.
This might seem like a specialised case that would never appear in the field from real world application, but that is not the case. I have dozens of such jobs from customers displaying exactly this problem with varying workarounds by producers such as (Agfa Apogee Normalizer), (Acrobat Distiller 6.0 $Windows$), (Adobe PDF library 7.77), (Creo Normalizer JTP ver. 3.1.6), (Adobe PDF Library 8.0).
In more detail, the job has one radial shading pattern using a stitching function with 6 child functions. The first child function coincides with the function domain, as do the last two child functions. The domain of the shading is a subset of the stitching function, arranged so that the end child functions should never be evaluated.
I believe the whole of the shading should be a solid cyan because the domain is 0.3 to 0.7. Only one of the child functions covers this range which is solid cyan. Acrobat displays the inner extended region as black which can only be explained by pushing 1 through the first child function, and the outer extended region is yellow which can only be explained by pushing 0 through the final child function.
I believe Acrobat should be using the shading domain limits for the extend regions. Instead, it is using 0 and 1. But worse, the values are being used the wrong way round.
This is my hand-crafted job for testing shading patterns with Type 3 functions. The job is hand crafted, and I haven't gone to the trouble of setting the xref table or setting the stream lengths, but Acrobat does repair the file and it behaves the same as other, real-world, jobs

Philip, thankyou for offering to look at this.
I have attached 'FunctionType 3 boundary.pdf' which was the original file I attempted to post. The file 'AcrOut Domain 0_3-0_7.png' makes it clear what I am seeing in Acrobat. I would also like to augment my original post a little to point out incompatibilities between Acrobat and CPSI.
1. From my PoV, compatibility between Acrobat and CPSI is important, so I've also attached a file that contains equivalent PostScript. On my Ricoh Aficio with CPSI (3016.203) inside it, the job is rendered in solid cyan as I would expect given that the domain of the shading is restricted to [0.3 0.7].
2. If the jobs are changed to make the shading domain [0 1] instead of [0.3 0.7], Acrobat displays a green ring (expected), and the inner extend region is now red (expected). The outer extend region remains yellow.
CPSI renders the job almost the same as Acrobat, but the outer extend region is painted in cyan, not yellow. An Nth reading of the PDF and PS specs has revealed a subtle difference; there is one sentence in the stitching function section of the PDF spec not present in the PS spec, it is "If the last bound, Bounds(k−2) , is equal to Domain(1) , then x′ is defined to be Encode(2i)". I take this to mean the outer extends region may have different color in the PDF and PS versions by design.
3. If the pdf job is changed to make the shading domain [0.01 0.99], Acrobat displays the inner extend in black as before (unexpected), otherwise the same as 2).
To summarise:
1. There appears to be a bug in Acrobat whereby it ignores domain of the shading when painting the extend regions.
2. There is an incompatibility between Acrobat and CPSI in the outer extends region when the final Bounds entry is equal to the Domain value. This may be by design.

CS5 and stitching

Just out of curiosity, I'm wondering if the new Photoshop CS5 changes/improves anything in relation to its stitching capabilities...?
I'm a landscape photographer and I would like to more fully take advantage of the stitching opportunities and capabilities of Photoshop. Just wondering if anything new has been added to the latest version of Photoshop (as opposed to my CS3 version, which I've been using for quite a while now, of course).
Thanks in advance for any and all info!

Hi Hud,
      Hmm, sounds like the Paul Newman movie.
      My PTgui is very old now. Joost has a 64 bit version that looks pretty souped up and I would love to have it.
      Yeah, I have lost a few shots my not locking the camera settings but I learned a long time ago to do it, and
it will save your butt. Both of the camera bodies I have only shoot 6.3 mgp so it limits my printing size to about
11" tall and what ever length it goes to. Its fun when I can find something interesting to shoot. Lately is all just
school work and I am tired all the time from it.
     I just worked over a single IR shot I did with the Canon 10D. The big issue is the noise. I converted the image
to CMYK to look at the channels and found a way to balance the yellow and red so the noise is minimalized in the
sky. I could not do it well in RGB. It shows up in the sky more and I like smooth skies. Previously I had used the
blur tool to soften the noise in the background and then sharpen the forgrounds subjects.
     The new issue of Color is out and it has some nice images in it.
     BTW, there is a new hardcover edition of the color photography of Ansel Adams. Check it out. I love his hilltop
Colorama! I would love to shoot images like that but suspect it would take a Brightlite size sensor to achieve it.

Subject: Re: CS5 and stitching
Your PT is newer than mine. I would have had to pay for the upgrade, but even by the time CS3 arrived, I decided that most of my stitching does quite well between both tools.
On CS5 take a set of images previously stitched in PT, redo the stitch in CS5 using the Auto(Default) button and checking the Geometry check box at the bottom. So far as the vignette check box, I found no difference checked or unchecked.
I also use DXO for lens correction which includes vignetting correction based on camera and lens combo. Again, doing stitching with either an uncorrected set or one that is corrected, there is a difference but sometimes I prefer the corrected, sometimes the uncorrected. I'll be interested in what CS5 can do when that feature is unleashed. I hope I can turn it off before stitching, if I so desire! And I also hope that it isn't auto on everything, because it will likely double correct the dxo files!
Using pano to generate a grid and not just a panorama is a great way to up the quality from early digital sources. But I stand by my comments that, given optics capable of generating the same angle of view as a single shot, or through collected frames as a grid, the D80 showed improvement at the 16x20 print size, the D90, practically none.I believe it has to do as much with intrinsic noise as optical properties, and at 1600 ISO, D90, I would do a set to stitch as a backup on important shoots.
A caveat: I have lost a fine set of images to stitch because one frame lacked the sharpness of the others, even using VR lenses. So be careful. Nothing more ghastly than a great image with inexplicable lack of sharpness in a portion of the final!

This may be an issue with the pde plugins. PDE stands for print dialog extension and are included with vendor drivers to provide access to printer features not supported by the core printing system. If you are using a Power PC driver (or sharing it from the G4 to the MacTel) then that may be a possible cause. See if HP offers a Universal Binary driver for your model.

Web of Trust no longer working with google and bing image searches

Hello All,
I have searched and searched but have not found an answer that matches my specifics. Any help would be appreciated.
I used to be able to do this but now I can no longer search and browse images on google or bing image search and have Web of Trust function. Here is how I am going about it.
What I use:
DuckDuckGo's annoymous google or bing image search link when I enter querries. Also, searching directly from Google's or Bing's image search page doesn't work with WOT anymore either.
Firefox 23.0.1
The following add-on's:
Add-block plus 2.3.2
BetterPrivacy 1.68
Flagfox 4.2.12
Ghostery 5.0.4
Google/Yandex search link fix 1.4.1
No Script 2.6.7.1
Web of Trust 20130515
If anyone has a fix for this please let me know.

I guess what I learned is that sometimes the best solution is to do nothing and wait for the problem to solve itself! Funny, this has never worked for me before.
WOT is now working for me but often for only the first few rows of images. That's cool that it is also working with bing images.
Boudica, thanks for understanding. I am new contributor/ question-asker here on mozilla and may not understand how things are done. I was just frustrated, getting an email saying that my question was answered, logging in to find that it wasn't.
Now we have the functionality that we wanted, right?

someone may be able to help you (not necessarily this poster, who is not a Windows user).
a screen shot of your settings or of the image could be very helpful too.
