Need help emergency! In my Vision Application, how to extract the specified curve settings from the geometric template which was generated by NI Template editor??

I have a machine vision application, in which the geometric pattern match technique was used to find the target in variant images.
as we know ,we have to make a geometric template by the NI Template editor, in the editor we can adjust the parameters of specified curve settings to get the wanted curves, and we can draw the custom area to ignore during the match. then we save the template for latter using in our vision application.
Now my question is coming. when I program my application for the geometric match. I have to specified the Curve Parameters for the input of IMAQ Advanced Setup Learn Pattern 2, obviously, I have to set this parameter same as the one in the template, but I don't know how to extract it from the geometric template. I have tried all methods I can, for example, read custom data, IMAQ Get Geometric Template Features(this is just for the feature based? then is there a same VI for the edge based?) , even to anasys the PNG file formats!!!! But I can not read the geometric template info by myself!
It is too illogical that we have to adjust the CURVE PARAMETERS manually again for the " IMAQ Advanced Setup Learn Pattern 2"after I have already done that in the NI Template editor !!!!
Solved!
Go to Solution.

Hello,
why do you need to specify the curve parameters again, if you have already built a template using the template editor?You do not need to use "IMAQ Advanced Setup Learn Geometric Pattern 2 VI" to find the matches (see the attached example).
you can wire the control to the "curve parameters" to the "IMAQ Setup Match Geometric Pattern 2 VI", but the values are not used if you wire a true boolean to the "use learn curve parameters" node (it is like this by default). To prove this, i have attached a small program, with pre-created template (using the template editor) for geometric matching. The template and three test images are also included.
Try changing the curve parameters with the "use learn curve parameters" enabled, and you will see that the matching score remains the same. Then disable the boolean control and try changing the curve parameters.
Also take a look at the detailed help for "IMAQ Setup Match Geometric Pattern 2 VI", specifically the "Use Learn Curve Parameters".
I hope this helps.
Best regards,
K

How to reverse the Batch number which was enter wrongly during GRN posting

Hi Folk,
How to reverse the Batch number which was enter wrongly during GRN posting .
Please revert.
Thank you.

You can either do a transfer posting and move quantity from this batch to another batch e.g. in MB1B with movement 311, or you cancel the entire material document using MBST transaction and redo your receipt correctly.
Then you can flag the wrong batch for deletion in MSC2N.
The batch itself gets deleted physically with the archiving transaction SARA object MM_SPSTOCK

How to create the SWF file which was included surrogate pairs.

I would like to make sure how to create the SWF file which are included surrogate pairs.
The error of outside the scope of unicode occurred when I compiled(mxmlc) the as file which was set surrogate pairs to 'Unicoderange'.
Ex, I set the ' '(UTF-16 is '20B9F') to 'Unicoderange'.
However, I cannot add the surrogate pairs.
The error of outside the scope of Unicode occurred when I compiled the AS file.
The reason of error was that the Unicode(UTF-16) of surrogate pairs is invalid.
Then, I read the following pages.
These pages are written that unicode-range supported surrogate pairs.

http://www.w3.org/TR/1998/REC-CSS2-19980512/fonts.html#descdef-unicode -range
So please let me know how to create the SWF file which are included surrogate pairs.

I've been able to create project jar files in Eclipse by selecting Export from the File menu, then choose Java - Jar file - and provide the required information, name, destination folder etc. But when I do this, I do not export other jars on the build path this way nor do I expect to do this. I am only concerned with creating a jar file of my own work. A jar file does not "contain" other jar files. If the jar file contains the main method, and requires other jars for it's execution, then you may wish to include a reference to required jars on the class path entry of the Manifest file of the jar file you create. I'm not sure how to create a Manifest file in eclipse though..

How to find the transport request which was released to Quality

Hi Friends,
Could anyone please let me know, how to find the transport request that was already released from Development to Quality?
there was some change in customization took place. I could find the user (through change log) who made these changes, however I could not find the transport request number he has already released. I did give his user name in SE10 and checked the released checkbox and did click transports to see them, however I found nothing. A message got displayed on the screen: Cross-system information for user xxx. I can't ask the Basis people about it, as its not yet been trasnported to Productive.
Is this the correct way to see the transport request number? Is there any other way to find the number. I can give the tentative dates when the change was released.
This post might already posted before, I did some search, could not find the exact info what I am looking for. Would appreaciate if anyone could give the step by step method to find it.
Thanks in advance.
BR,
Sats.

Ram,
let me tell you the the situation in a better way.
When I see se10 with my user id I could see all the transport requests that I have released. However, now when I enter my colleague user id who did these changes (he is on vacation, otherwise I could simply ask him the transport number), nothing is shown on the page. in simple words the page is completely blank. Initially I thought it is because of some authorizations, but I can get the transport request numbers that are released by another user.
the info what I have right now are:
1. I knew the user name who did these chages
2. I knew the date when it was changed.
I just need the Transport Request number I mean which starts with DEVXXXXXXX.
As per your solution --> If you have any idea when the reques was relase you can select the request and click on goto-transport logs. This way you can find out the request. --> I knew the date when it was released, but didnt understand, the bold and underlined sentense in your answer.. select on which request? as I said, the page was blank after I enter his user id and activate it.. May be I did not understnd your solution properly. Could you please simplify it.
Thanks a bunch in advance
Sats.

Sorry Guys,
Just came to know that there are methods to retrieve key and value on which the event occurs.
public void entryDeleted(MapEvent evt)
System.out.println(evt);
String key = (String)evt.getKey();
Person value = (Person)evt.getOldValue();
System.out.println(evt.getKey());

I need helping using iAds in my application.

I need helping using iAds in my application. I currently am not using any storyboards. I am using Sprite builder for my UI.
I attatched an image ot show all the different file name I have.
Everyone is being used & they all work fully.
The "iAdViewController.h & .m" files are just example codes I looked up and was messing with so that my iAd can work.

I wouldn't even be able to use the Mathscript node in an executable?
What I am trying to do is make a user configurable data stream.
They tell me how many bytes are in the stream and what parameters they
want to be put in to it. Currently I have to make vi's that are
called dynamicaly to make the parameters.   Then recompile
the code and send it to them. This is somewhat of how the config
file is set up so I know how to make the data.
Data_Type foo
Bytes 30
parameter_name
function
   byte#          format
sync
foo_sync
29               int
time
foo_time
1,2,3,4    double
If I can't use MathScript to allow the user to make there own functions
is there another way that I might be able to do this so I do not have
to recompile the code atleast? Were I might just be able to make
the new function and send that to them.
Any Idea would be great.

And when I open up MMAPI Demo and go to simple player, and then URL and paste this in, it plays the simple rtttl/midi file. It is doing this through RingToneConverter.
Now all I want to do, and this is the part I need help with, is while it is playing, I want the notes to be displayed on screen. Can anyone help me with this! I have tried and every time is gives me a problem saying that the RingToneConverter Class isn't abstract and I cannot print to screen...
If someone could help me with this, it would be greatly appreciated.

i need help to activate my iphone 5s. am stuck on the activation page. can someone help with with the icloud activation bypass? how do i even go about it?

You must put in the required information. If you do not have it, you must get it from the original owner of the phone. If you have forgotten your iCloud password, you can reset it at:
https://iforgot.apple.com/password/verify/appleid
There is no such thing as an activation "bypass". Activation Lock is a security feature. It wouldn't be that secure is you could bypass it, wouldn't it?

I need help with a PDF file that is an image, the "Read Out Loud' option does not work, please help!

I need help with a PDF file that is an image, the "Read Out Loud' option does not work, please help!

You mean an image such as a scanned document?
If that is the case, the file doesn't contain any text for Reader Out Loud to read. In order to fix that, you would need an application such as Adobe Acrobat that does Optical Character Recognition to convert the images to actual text.
You can also try to export the file as a Word document or something else using ExportPDF which I believe offers OCR and is cheaper than Acrobat.

Need help in multisim 11? I want to get the transient response of RL circuit....

Need help in multisim 11?
I want to get the transient response of RL circuit....i can get the increasing exponential graph in multisim 7 during simulation.....but i am getting a decreasing exponential curve(i.e,decay response) in multisim 11 when i do the same procedure as i did in multisim 7.....how can i get the initial or growth transient response for RL circuit in multisim 11 so that i can get increasing exponential curve....which satisfies time constant = L/R

Hello,
The process is the same for any circuit (in this case it is an RC circuit which you sent me). You can find the response on the voltage (which I think it's what you're looking for) at any point of the circuit, as well as any parameter really (R,V,I,L..etc).
Please refer to the image attached (an analysis on the voltage at an inductor and the wires connected to it).
The way to set it up (once you're in the transient analysis set up) is, select the Output tab, under Variables in circuit, you can select which parameters to take. V(1) and V(2) refer to the voltage in the circuit at Net 1/2 (or wire 1/2).
This differs from the voltage change within the capacitor/inductor/resistor. If you would like to see the voltage change of an inductor/capacitor/resistor/etc, you can select under the More options box, the button Add device/model parameter, which will take you to a window to select the device type, its name (in the circuit) and the parameter which you wish to analyse. Once you click on Simulate, you can select Cursor >> Show Cursors, to view information for y and x axis (like rise time, decay time, voltage difference...etc)
Hope this helps,

How to insert application form id into the form template

Hi,
Is there a way to set the application form id into a form template designed from the LiveCycle Designer? Here is the detail description of my question:
(1) I am using LiveCycle Design to design a form template.
(2) I go to our application to deploy this form template. During the process, a form id will be generated and it will be associated with this form template.
(3) I would like to insert this generated form id into the form template, so that later when user fills out and submits the form, I will know what's the form id the submitted data belongs to.
Appreciate you kind help!!!

Hi Justin,
Yes. The form ID will be generated by our application during the form deployment process (after the form is designed, it needs to be deployed to our application before it can be used.). So I was hoping there is a way to set the form ID into the form template design at that point. So that later when end user fills out and submits this form, I will know what form ID it is related to.
If I cannot do this at the deployment point, one way I can think of is to do it at the time when end user is downloading the form. I can return a "rendered" form (instead of opening up the form template directly) with the form ID information in it. But that means for every single form user opened we need to render it at run time to fill in the form ID, which is not performing and what I was trying to avoid.
Thanks for your help!

Need help using dbms_scheduler to submit an immediate job on the database

Hi. I need help using dbms_scheduler to submit an immediate job on the database. Essentially I want to issue a one-time call to an Oracle Stored Procedure - this procedure will then send an email. I've never used dbms_scheduler before, but here's what I have so far.
So my Program is a stored database procedure named 'TTMS.dropperVacationConflict_Notify', but my problem is that I need to pass 3 parameter values to this job each time I run it. This is what I can't figure out. The procedure expects an 'Id' as number(5), begin_dt as a date, and end_dt as a date.
How do I pass these values when I run my job? Can anyone help?
begin
    dbms_scheduler.create_program(program_name=> 'PROG_DROPVACCONFLICTS_NOTIFY',
     program_type=> 'STORED_PROCEDURE',
     program_action=> 'TTMS.dropperVacationConflict_Notify',
     number_of_arguments => 3,
     enabled=>true,
     comments=> 'Procedure to notify PCM of a Dropper Vacation Conflict. Pass in Dropper Id, Begin_dt, and End_dt');
end;
begin
    dbms_scheduler.create_schedule
    (schedule_name=> 'INTERVAL_EVERY5_MINUTES',
     start_date=> trunc(sysdate)+18/24,
     repeat_interval => 'freq=MINUTELY;interval=5',
     end_date => null
     comments=> 'Runtime: Every day all 5 minutes, forever'
end;
begin
    dbms_scheduler.create_job
    (job_name => 'JOB_DROPVACCONFLICTS_NOTIFY',
     program_name => 'PROG_DROPVACCONFLICTS_NOTIFY',
     schedule_name => 'INTERVAL_EVERY5_MINUTES',
     enabled => true,
     auto_drop => true,
     comments => 'Job to notify PCM of Dropper Vacation Conflicts'
end;
/And I use this to execute the job as needed...
begin
    dbms_scheduler.run_job('JOB_DROPVACCONFLICTS_NOTIFY',true);
end;
