David,
I probably want to implement e.g. "Canny Edge Detection":
http://cs.nyu.edu/~cil217/Vision/vision_edge_detector.htm[^]
Otherwise, I'd like to find the algorithm/code (C/C++) for either "denoising images" or "deblurring images".
Any pointers where I might find some code? It needs to be very basic though... preferably no more than 1 or 2 CPP files.

Other than searching for them, I've no clue. Image processing is not something I've ever done.

this is not as easy as it sounds depending on what you are trying to do. However, sharpening and smoothing are simple matrix operations. http://www.vbaccelerator.com/codelib/gfx/imgproc.htm[^] (sorry for the vb reference, first one google turned up)

You know those whack-the-mole games in the kids section of an arcade? Well - I suggest you create a whack-the-mole game. Only instead of a mole, use Michael_Chertoff's[^] face. A large mallat as the mouse cursor, and a 3x3 grid should suffice.

Actually, you've probably got nothing to worry about. It's much like the safest place to be when a new driver is on the road is in the middle of the road itself, or the safest place to be when out with a new hunter is in front of the target.

Hi, how can i build a program to monitor the registery modifications (hooking advapi.dll)
Hayder Yousif

I don't know but Microsoft's regmon.exe application manages it no problem. As they're no longer allowed to hide private APIs for their own use, at least in Europe, you could try to find out how regmon works. Hooking ADVAPI sounds plausible but my guess is there's a better way.

I want to Print An Image Buffer(640*480) in MFC dialog application.
I can print but, size of Printed Image is not (640*480).
How can I solve the problem? Probably in mapping Problem.
I used :
void PMCToolDlg::OnPrepareDC(CDC* pDC, CPrintInfo* pInfo)
{
if (pDC->IsPrinting())
{
pDC->SetMapMode(MM_ISOTROPIC);
pDC->SetViewportExt(7, 7);
pDC->SetWindowExt(1, 1);
pDC->SetViewportOrg(0,0);
}
}

And where are you creating the compatible bitmap to the equivalent size of your dimensions in that mappin mode?

I see one problem immediately...
From the docs:
"When MM_ISOTROPIC mode is set, an application must call the SetWindowExtEx function before calling SetViewportExtEx"
mazhar_cse wrote: size of Printed Image is not (640*480).
Assuming you get the DC set up properly, and you're not stretching the image
when you render it to the print DC, the resulting image dimensions should be
4480 x 3360.
As far as the size on the printed page - this could be anything.
You haven't taken resolution into consideration here.

what we use to handle exceptions in Macintosh programming (xcodeproject)
b'se try and catch(...) never work for MAC. They never caught any exception
Manoj Kumar Chauhan

Exception handling is a cooperative effort between the OS, the C Library, code injected at compile time by the compiler and your code. One of these is not doing its job. Your next step probably needs to be to find out which. Make sure that C++ exception handling or SEH or both are enabled in your project, that should take care of the Compiler. Make sure if you need SEH that your OS supports it. Make sure you're using a C Library like MSVCRT that has the necessary support in it for Exception handling and if necessary rebuild it with different options to support your OS and the exception handling you need. If all this is good you should be able to debug the exception handling process itself, at least at the assembler level and get some idea of what is and isn't working. All sort of things like switching off Thread Local Storage support can break exception handling, even mixing code compiled on different Visual Studio versions. If your stack works differently on the MAC then stack unwinding is different, even processor register map differences could in theory break an implementation. EH is still a black art I'm afraid and you may need to get your hands dirty if your root problem is not straight forward. Good Luck

Hi,
my compiler is gcc and environment is xcode
I have enabled c++ exception, c++ runtime type, objective-c exceptions and statics are thread safe. But still the exception is not catch. What is SEH? I did not find it.

I know very little about gcc or and even less about exception handling with gcc or xcode so my advice may not be good. Still I would stick to strict ANSI C++ exception handling rules as that is what gcc is most likely to support. You can forget about SEH (Structured Exception Handling) it's an Operating System exception mechanism which may not be available on the MAC and almost certainly not under gcc.
What will work under gcc pretty much anywhere are Standard Library exceptions. Have a look at std::exception and derived classes to see if you can get any examples to work. If you can get a std::exeception to work you can debug through what it does and see how it uses primary exception handling internally. This should give you what you need even if you can't use std::exception directly. Good luck.

Ok Thanks for this info. I think there is some problem with gcc compiler or some special setting which i dont know. I create a new program just to handle divide by zero exception. In project setting i enabled c/c++ exception. In prepocessor macro following line was written
_APPLE_C_SOURCE _NO_EXCEPTION
it prevents the exception. So i removed this line. Also in my program i add following
#undef _NO_NAMESPACE
#undef _NO_EXCEPTION
#undef _NO_TEMPLATE
But after this exception is not caught. Program is simple like
int main(void)
{
try{
vector<int> a;
a.push_back(1);
a.push_back(2);
vector<int> b;
b.push_back(0);
b.push_back(0);
for(int i = 0; i <a.size();i++)
{
="" if(a[i]="" b[i])
="" a[i]="b[i];
" }
="" catch(...)
="" printf("exception="" caught");
="" }
}
i="" think="" there="" is="" something="" which="" should="" be="" define="" in="" preprocessor.=""

You may well be right. I would be interested to know what it is. It is also worth noting that on some system math exceptions are handled separately. A 'divide by zero' exception may be considered a special floating point exception and be handled by the math library. Check this out if you are using glibc or stdlibc. It's possible that your exception is being handled somewhere but being filtered out before reaching your handler code.
