How to deconvolute an image when the line spread function is known

I want to deblur images with a custom filter. Therefore I took images of a sharp edge, which gives me the line spread function (and so also the point spread function)
It must be possible to derive a deconvolution kernel from this, but I don't know how.
Or should I do it in Fourierspace?
Thanks in advance!

I would think that the best way to do this is to use a deconvolution matrix. You can find out how to calculate the matrix in most vision books. There is a general formula.

Ejecting the stuck disc can usually be done in one of the following ways:
1. Restart the computer and after the chime press and hold down the left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.

How to send multiple attachments when the number of attachment is known at

I am creating an independent E-mail component for an n tire architecture. This component gets the email message and files_to_Attach as method parameters.
Files to attach is inside an array list.
So the number of files for attachment is known only at run time.
How can I attach this files.
If I use single instance of MimeBodyPart (ib side a Four or While loop), it attaches the last file several times.
Please advise me on this

How to enlarge the image when the mouse is clicked

I want to enlarge the image when the user click the image. How to do it by muse? Thank You!!!

Hi,
When you create a page in Muse called "Home" or "Gallery" or other else, when you export your site as HTML you must have a file called "home.html", "gallery.html" or "other else.html". Remember in what page you putted the Gallery in Muse and edit it with notepad, wordpad or similar and find the code where the gallery is linked (search the name of one of your images, is the best way to find it) and replace the code with something similar like that:
<code>
<a href="images/medidas06.jpg" rel="lightbox[gallery]"><img class="block ImageInclude" id="u3527_img" data-src="images/medidas06.jpg" src="images/blank.gif" alt="" data-width="248" data-height="360"/> </a>
</code>
The path to the JPG files must be ok with your website.
The other steps are well explained by the readme of the lightbox library

How can I generate data when the link is click on?

I think you need to rephrase your question and be more specific. Also for me the images you are referring to do not exist. From your question I am interpreting it as "how do I program?"

My iPhone 3g has 2 white horizontal lines i don't know where did it came from. I turn it off then on but its still there. the lines spreads everyday. I dont know how to fix it. need some help guys.

my iPhone 3g has 2 white horizontal lines i don't know where did it came from. I turn it off then on but its still there. the lines spreads everyday. I dont know how to fix it. need some help guys.

If you take a screenshot (Press the home button and Lock button at the same time), does it appear on the screenshot? Zoom in on the screenshot and see if it's still there.
If not, then your display is failing. I would recommend taking it to an Apple Store if you can, if you can't then to an authorised Apple reseller.
If it does appear on the screenshot when you zoom into the spot, then it's a really weird software issue! You might have to backup and restore the device.
Let me know!

How to deal with images when detecting/resizing screen?

Hi there,
I am trying to learn how to detect screen resolution and
resize a flash movie to those dimensions. The one thing I'm
wondering first is, how to deal with images in the movie.
Do I need a variety of different movie sizes that I serve up
depending on the resolution, or is there some way of linking to
higher rez image that can be scaled down to fit the screen?
Thanks!

as far as I know this has always been a bit of an issue when
using
images inside a scaled movie. If you display a high res image
inside a
scaled down movie, flash can't "reoptimize" it so the image
looks
jagged. Of course the other way around is even worse..
Serving images based on the screen res could be possible if
you detect
it using javascript but could be a night mare to maintain and
test it...
I guess the questions I would ask myselkf are:
1. what is my audience? What resolution the majority of them
will have?
2. Is there anyway I can keep the image size fixed, and scale
to fit he
rest of the design?
3. How much time do I have to implement the customized
version?
It really depends on your project..but to answer to your
quuestion yes
you can detect.

and your flash will have to interpret and load images from
different
directories based on the var passed

How to debugg a script when the Required out put is like Fax or email

Hi this is Durga Prasad i have small doubt in scripts can any one clarify that one plz normally we will do that one with activating debugger but when a special requirement is like fax or e mail how we will do that one

Hi
DEBUG Smartform:
1) One way to debug smartform is to debug the Function Module of that smartforms.
If you want to debug particular smartform node that the solution would be,
insert a "Program Line" just above the node you want to debug and this program line write a normal abap breakpoint.
So whenever you call the smartforms, it will stop at this breakpoint and you can debug onwards.
2) SFTRACE can be used for debugging SMARTFORMS.
Read More here.
http://help.sap.com/saphelp_erp2004/helpdata/en/49/c3d8a4a05b11d5b6ef006094192fe3/frameset.htm
script
1). Use Tools - Word Processing - Layout Set (SE71). Enter name of layout set and then Utilities - Activate Debugger.
It is of no consequence which layoutset you enter when selecting the SAPscript debugger. (Menu path: Tools-Wordprocessing - Forms, Utilities - Activate Debugger) The next layoutset called will invoke the debugger.
2). Another way to set the SAPScript debugger is to run program RSTXDBUG.
When you debug Print program it is same as you debug any other ABAP program. While when you debug SAPScript, you actually debug the code ( scripting) you have written SAPScript Form.
As per ur question there is nothing new with script debugging,
it is same as normal report debugging...
SMARTFORMS DEBUGGING
For smartforms debugging you can do this.
1. Execute the smartform (execute button in SMARTFORMS transaction)
2. Take the generated function module and display it in SE80.
3.Find the smartforms Elements (text elements, windows, code lines, loops) in this and set Soft break points.
Correct name is SMARTFORM_TRACE. You have lots of options for adequate analysis
Tcode - SFTRACE
Re: How to Debug a Smartform
Debug of smartform and sapscript.
Debugging SmartForms
Debugging of a subroutine pool.
SCRIPT
There are 2 separate kinds of debugging available when you try to debug scripts.
1. Debugging the print program : This is the normal debugging we do for our report programs.
2. Debugging the script itself : You Can debug a SAP Script by activating debugger in two ways:
a .In SE71->Menu->Utilities->Activate Debugger, then debugger will be get activated and when your print program is executing Script Debugger will be in active and you can proceed with your debugging.
b. Goto se38-> RSTXDBUG ->Execute this same as going thru in se71-> Menu, now debugger will be activated.

How to apply an image to the back face of another?

I am only fairly new to motion but am, learning fast. I'm wondering if someone can tell me how to apply an image to the back face of another image?
I'm trying to animate a brochure opening and want to apply the front cover as the back face to the page I'm opening to (each page is a separate .pdf file). I know this can be done easily rather than animating them as 2 separate objects, i just can't remember how to do it.

Thanks Mark. That is how I will do it if there isn't a simpler way. I could have sworn i have seen the option to allocate an image as the back face to another image. So when it animates, you automatically see the other image on the reverse side?

How to have multiple images on the same screen? like in the movies where you see several actions at

how to have multiple images on the same screen? like in the movies where you see several actions at the same time ....
i don't find a tutorial in adobe tv....
thanks !!

The short answer is that you'll put the source clip(s) for each inset on a different video track, all stacked up. Then use the Scale and Position effects (under "Motion" on the Effect Controls panel) to reduce their size and place them where you want.
If the content of an inset will involve edited content (where you're cutting among various clips or just trimming out unwanted content from a single clip), then you'll probably find it easier to do all those edits in one sequence, then nest that sequence in the master sequence, where you apply the Scale and Positioning effects. That will save the step of applying the scale and position effects to each edited track item.

I thought that at first, but I have text this person before and had received responses in a timely manner. Its just weird that it all of a sudden removed their name.
Would this affect the delivery of the text message?
