How to detect solar cell out of image

Hello All,
Sorry, I have post this question on other forum but didn't get any answer. Please help me in this task. Actually, I am trying to detect the solar cell out of image and I thought making a histogram of the image could be a step one but I am no where now. Could you please provide me an example of similar task which can be helpful. Thanks
Regards
Solved!

Your original thread is not dead.  I propose to close this thread and stuck with the origin.
Hell!  In the meanwhile the other thread references this one.  It seems you now have to maintain two threads for one issue ...

  • How to detect the size of an image

    Hi,
    I have a servlet which grabs an image (jpg or gif) from a BLOB stored in my database and sents the image back to the client through the ServletOutputStream. This all works good and the image is presented nicely. However, I now want to have my servlet detect the size of the image, and if it is too big resize the image and return it.
    As I am new to images in JAVA I am unsure how to do this and what tools to use for it. I found some information on JAI, but this seems way to elaborate for what I need. Please let me know if anyone knows how to do this.
    Thank you and regards,
    Joost Schouten

    This code figures out the size of any object in bytes. I am not sure about resizing the image though..
    public int getSerializedSize(Object object)
           try
              ByteArrayOutputStream baos = new ByteArrayOutputStream();
              ObjectOutputStream oos = new ObjectOutputStream(baos);
              oos.writeObject(object);
              byte[] bytes = baos.toByteArray();
              oos.close();
              baos.close();
              return bytes.length;
           catch(Exception e) //not good
              e.printStackTrace();
           return -1;
         }Rishi

  • How to detect alterations to a JPG image that has been saved as a PDF

    I have received a file containing a cancelled bank check that was downloaded from a bank website and saved as a PDF of the screenshot. Upon opening the PDF, it appears that some of the original hand-written text in the image has been altered. I believe this PDfFwas originally saved as a JPG, then altered, then saved as a PDF. Is there any way to determine if indeed the text has been altered in the file? Thanks!

    Not easily.  The bank's original version may have been a JPEG, then a screenshot was taken of that and saved as a PDF with unknown compression.  (really, who saves a screenshot as a PDF?)
    You can examine the PDF in a text editor to see what created it.  You can open it in Illustrator to see the layer data (which might show tampering).
    Beyond that you'd need an imaging forensics expert to look for tampering with the JPEG compressed image data (was it compressed more than once, was something significantly altered)?

  • How  do the dynamic state to record image in the cell-phone?

    Excuse me.How do the dynamic state to record image in the cell-phone?Or whether it has the feasibility or not?..Somebody can give me some opinions and data,please.
    Thanks.

    I don't understand very well what you want, but to record and image (get and snapshot) you have to create an Player, realize the player, start it and then get the snapshot. ex:
                player = Manager.createPlayer("capture://video");
                player.realize();           
                VideoControl videoControl = (VideoControl) player.getControl("VideoControl");
                player.start();
                byte[] data = videoControl.getSnapshot(null);
                Image image = Image.createImage(data, 0, data.length);To find out if a device can record images you can use this:
                boolean mmapiAvailable = System.getProperty("microedition.media.version") != null;
                boolean canGetSnapshots = System.getProperty("supports.video.capture") != null;Hope that answer your question.

  • Does any body knows how to detect the resolution of an inserted image in word?

    Does any body knows how to detect the resolution of an inserted image in word?

    I'm not sure I understand your reply but when you insert images into Word that are larger than will fit on the page, they are automatically compressed. If you right click and select Size and Position you can restore it to 100% but you will not see all the image.

  • Iphoto is blacking out vertical images when importing.  how do i fix this?

    iphoto is blacking out vertical images when importing. how do i fix this?

    There are 9 different versions of iPhoto and they run on eight different versions of the Operating System. The tricks and tips for dealing with issues vary from version to version and OS to OS. So before anyone can help, they need information to work with. Things like:
    - What version of iPhoto.
    - What version of the Operating System.
    - Details. What were you doing when the problem arose?
    - Did it ever work properly?
    - Are there error messages?
    - What steps have you tried already to solve the issue.
    Anything else you can think of that might allow someone else to understand your issue.

  • How indesign detects that the images have been modified

    Hello,
    My problem is that all my images links are seen modified (yellow triangle) while the images don't have been modified.
    The modified dates are the same.
    All my images are on a unix server and indesign is used on Mac.
    How indesign detects that the images have been modified ?

    Thank you for your answer.
    When you say the time stamp you talk about the modification date in the box link info ?
    Because this date is the same on the image and in indesign and when I update the image this date doesn't change.
    the only informations that change when I update the links are the import date and the state (modified become ok)

  • How do I display call out accessories with different images?

    I need some help with an app I'm developing.  I'm displaying a map with an array of annotations.
    I have managed to display the map &amp; annotations successfully.
    What I want to do next is have call out accessories that display different images everytime they are tapped.
    Can anyone help with this? I have managed to display a right call out accessory but I'm getting stuck here &amp; I don't know how to get my code to display images.
    Any help wil be greatly appreciated!

    baltwo: Thanks for the tip, I didn't know how easy it was to set up custom icons in OS X. In this case it's a difficult solution because it will have to be done by hand for every single folder, which is a problem if I'm going to have these in two places. I'm new to Automator but there doesn't seem to be a way to have it; 1) Select all the folders in a directory. 2) Copy the first image in each folder to the clipboard and have it use that image as each folder's icon.
    Barney-15E: I know it sounds moronic, but yes. I've tried iPhoto but it's not a very good solution in this case. My folder structure is like this:
    Root -> 282 image folders with 10 to 60 pictures in each.
    All I really need is the ability to see at a glance what each image folder has without opening each individual folder. The folders are numbered sequentially (1-282 in this case) rather than by proper names, so this is the most efficient way.

  • How to detect "almost out of memory" in JRockit?

    I would appreciate any advice on how to build an "almost out of memory" detector to ensure the JVM does not crash when the user mis-configures our application.
    So far I have encountered these problems with JRockit 27.3 (JDK 5.0) in limited testing on windows. This test is just one part of the app, using only 50mb. I've tried 27.4 and it appears to have the same issues.
    1) Runtime.freeMemory returns 0 often, even when lots of memory is still available (28% was returned in the previous call!). If the thread sleeps for 30 millisec a resonable value might be returned. (but still gets 0 fairly often).
    2) There is huge oscillation in the free memory reported even when there is > 15% memory left. The test program allocates some intermediate data (10kb or so), then the more permanent data (500 bytes or so). Successive calls to free memory in the loop can oscillate from 8% left to 17% left.
    3) As memory gets more than 50% used, the GC algorithm switches around several times. I was using -Xgcprio:pausetime with pause time of 600ms. The observation was the GC algorithm switches and some full GC's would take as much as 8 seconds (this test using 100mb of memory) and during this time my polling thread (250ms) does not run. This is a problem since there are a couple of polling threads that expect to run at least once per second.
    4) It appears the basic Java heap usage is quite different with JRockit. The test code can allocate 50k result objects (about 500 bytes each) when run in Sun JVM, but only 33k objects in JRockit. (-Xmx is set to 50M for these tests, the real app runs with 3 to 12GB based on customer hardware)

    Can you post your test code here?
    Thanks,

  • How about putting out ISO images for various downloads

    I posted this suggestion before, a year ago, I think. no change. so here it goes again:
    It'd be much better to put out ISO images instead of.cpio.gz or .tar.gz file, as
    many people I know had to extract the content from the archive, then generate cd images.
    There are great free ('mkisofs') and commercial tools to generate iso images.
    One may argue that it'd be hard for people don't have cd-rom/cd-rw. Under linux, this is not an issue. iso image can easily be mounted on a loop device and read from.

    Hi Nick, I do see information on creating a slideshow with Quicktime at: http://www.apple.com/quicktime/tutorials/slideshow.html
    however it appears Quicktime X removed that capability. There is no 'open image sequence' option from the File menu in Quicktime X.
    If I do end up sticking with Final Cut - would you recommend any codec and/or dimension size that would result in the best quality or the most crisp image? I also need a few fade in's and out's on various parts - I don't believe I would have the control without Final Cut.
    Would resizing the image files in Photoshop to 1920 pixels by 1280 before importing them into Final Cut result in crisper images? Thanks.
