Can I extract the imaginary component of an image if so how

I am using imaq vision and I want to introduce random phase into an image therefore want to know if it is possible to extract the phase from the image and then effectively add it back into the image or am I asking the impossible?

Miss,
This can be done in a number of ways. First, if you have the "random phase" image, you can just use the operators to perform the addition of the two images, then subract it back out as you need. You will have to generate the image, which is up to you.
Another way to do this, which would probably work better with generating the image, would be to take the image out of IMAQ and do the operations directly on the image data. You can either do this in LabVIEW, or Matlab. I have done operations of this sort (actually, batch processing) using mathematica. It was somewhat difficult to get LabVIEW and Mathematica talking, and most of the operation was actually done manually. I suspect that Matlab, or even HiQ could do the image manipulations you seek
, which means bringing the data back to LabVIEW is quite easy.
Good luck, and please keep us posted.

    DVD: can I extract the movie files?
    I created a DVD (burned on DVD media). I did not archive the project since the files are too large. Can I extract the movie files from the DVD? I want to make a edit to the DVD.
    I know if I have the movies (clips) in iMovie I can do it but how do I do it from a completed DVD that I created and dont have the assets?
    I really don't want to pay for software that I will use once. Low or No cost alternative that won't sacrifice file quality? Thanks! Steve

    As far as set up goes, others on this forum feel free to add. I rarely use either of the above (although I have access to them on separate power macs).
    Reason: Apple's DVDSP works natively with Mpeg-2. I personally have no need for anything else since these features are already included in apple's pro apps.
    Q: Doesnt DVDxdv watermark the demo version?
    A: Yes. It does, until you pay for it in full.

    Q:what is QT playback component??
    A:The QuickTime MPEG-2 Playback Component provides QuickTime users with the ability to import and play back MPEG-2 content, including both multiplexed (a.k.a. muxed, where the audio and video tracks are interleaved into one track) and nonmultiplexed (a.k.a. elementary) streams.

  • How can I extract the two channels from a stereo track?

    Hi,
    I am writing a class that is able to draw an audio signal. It seems to be working well but I have a question. If I load a mono audio file I am able to draw it on a graph by using the byte[] array and everything is ok until now. That's the code:
    void Draw(byte[] x)
                Graphics g=getGraphics();
                Graphics2D g2=(Graphics2D)g;
                g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,                     RenderingHints.VALUE_ANTIALIAS_ON);
                for(int i=0; i<x.length-6; i++)
                    g2.draw(new Line2D.Float(((i*(getWidth()-6))/x.length)+5, (getHeight()/2)-          ((x*(getWidth()-6))/x.length), (((i+1)*(getWidth()-6))/x.length)+5, (getHeight()/2)-     ((x[i+1]*(getWidth()-6))/x.length)));
    The results is correct only if I have a mono track. Obviously when I get a stereo track the array becomes very large so here the question. How can I extract the two audio channels from a stereo track?
    Thanks in advance.

    A mono audio stream is stored [sample, sample, sample, sample], so just a list of samples in an array.
    A stereo sample is interleaved in the same manner, so you get [left-sample, right-sample, left-sample, right-sample]
    So every nth sample is the 1st channel, every nth+1 is the 2nd channel...

    Hi Gurus ,
    How can I extract the data from a XSTRING  .
    I have to get the data which is filled in the survey form the data is getting saved in form of xstring .

    Please reply with the FM in case some one knows about it .
    Thanks in advance .

    The following code works as of 7.0 (in any SAP system):
    FORM XSTRING_TO_STRING USING input TYPE xstring CHANGING output TYPE string.
    TYPES : BEGIN OF ty_struc,
              line TYPE c LENGTH 100,
            END OF ty_struc.
    DATA lt_char TYPE TABLE OF ty_struc.
    DATA length TYPE i.
    length = xstrlen( input ) / cl_abap_char_utilities=>charsize.

    CONCATENATE LINES OF lt_char INTO output RESPECTING BLANKS.
    output = output(length).
    ENDFORM.

    Hello Maria,
    Well, in the Support Message window, place the cursor in Component box and press F4. This will brings up another window which contains the components list to which you are authorized. From that list you can choose about which component you want to create that particular support message.
    For example, if you are from Quality department, the following can be visible when you press F4.
    QM - Quality Management
      -- QM-ADB Adobe Forms
           -- QM-ADB-PRN Print Forms
      For the Print Forms, the component will be QM-ADB-PRN
    I hope it helps.
    Cheers,

  • Can't extract the Photoshop CS4 trial version archive

    Hello,
    i downloaded the Photoshop CS4 trial version with the help of the Akamai download manager and now i have some trouble to extract the archive. I tried it with the Adobe extractor, with 7-Zip and Win-Rar, but i always get the message that some files (about ~500 files) are corrupted.
    I downloaded the trial version (archive size 857MB) about 4 or 5 times from the Adobe website, but i always have the same problem. I can't extract the archive properly. Does somebody have a solution for my problem? Thanks in advance!

    The size I'm seeing for the English/Windows version of the PS CS4 Ext Tryout .7z is:  853,860,607 / 814.3MB which took 20-25 min to download on a 500-1000KB/sec connection at work.
    Using Test in WinRAR 3.80 trial says everything is ok.
    Some questions that suggest things to try:
    Are you on a wired internet connection all the way to your computer?
    Are you extracting from your local C: drive?
    Are you deleting what is downloaded each time before retrying?
    Have you turned off your virus scanner before downloading and/or when trying to extract the files?

  • How can I extract the native SQL generated by TopLink?

    How can I extract the native SQL generated by TopLink?
    This is useful for example to use pagination, or pass the SQL to a stored procedure that may do many things, like using a cursor, or apply security.
    Pagination example where the SQL inside the inner parentheses are generated from Toplink, and the outer SQL is generic:
    select *
    from
    (select xx.*, rownum as rn
    from
    (select o.order_id, r.name, ...
    from placed_order o, restaurant r
    where o.restaurant_id = r.restaurant_id
    order by o.order_ext_id
    ) xx
    where rownum < 21)
    where rn > 10

    Alternatively, you can open your sessions.xml in the Mapping Workbench and for a specific session, you can Click the Login Tab and then the Options tab. Then select "Native SQL" and it will be outputted to the console (assuming that is where you outputing it).

  • Can't extract the data from sourse system

    hi,everyone
       i have a question about extracting the data from sourse system.i created a general datasourse.in the r3 system,i used t-code:rsa3 to extract the data successful. but ,when i replicate the datasourse to the bw system,i can't extract the data to the psa. in the process of the extracting,accur a error like below:
    Errors while sending packages from OLTP to BI
    Diagnosis
    No IDocs could be sent to BI using RFC.
    System Response
    There are IDocs in the source system ALE outbox that did not arrive in the ALE inbox of BI.
    Further analysis:
    Check the TRFC log.
    You can access this log using the wizard or the menu path "Environment -> Transact. RFC -> In source system".
    Error handling:
    If the TRFC is incorrect, check whether the source system is fully connected to BI. In particular, check the
    authorizations of the background user in the source system.
    who can tell me why?
    thx
    zhang

    Hi zhang,
    Please check the below points.
    1. Perform the connection and authorization test in SM59 for the RFC connecion.
    2. Make sure the RFC user extracting the data is having sufficient authorization and correct profile as per note 150315.
    3. make sure there are sufficient number of Dialog process in BW in SM50.
    4. check T code SM58 in source system for any more errors.
    5. check the connection between the systems.
    Check
    Note 561880 - Requests hang because IDocs are not processed.
    Note 535172 - IDoc: Dup. IDocs in tRFC inbound processing w/ runtime error
    Note 555229 - IDocs hang in status 64 for tRFC with immediate processing
    Hope this helps.
