[] Medical Imaging Systems
In recent years, extensive research has been performed to develop more
and more efficient and powerful medical imaging systems. Such systems
are crucial for medical specialists, allowing a deeper analysis and to
understand what is going inside the human body, and therefore they play
an essential role for adequate medical diagnosis and treatments.
To accomplish efficient and powerful medical imaging systems, many
research works have being done in many domains, like the ones related
with medical image devices, signal processing, image processing and
analysis, biomechanical simulation and data visualization.
The main goal of the Workshop =93Medical Imaging Systems=94 is to bring
together researchers involved in the related domains, in order to set
the major lines of development for the near future.
Therefore, the proposed Workshop will consist of researchers
representing various fields related to Medical Devices, Signal
Processing, Computational Vision, Computer Graphics, Computational
Mechanics, Scientific Visualization, Mathematics and Medical Imaging.
The Workshop endeavors to contribute to obtain better solutions for more
efficient and powerful medical imaging systems, and attempts to
establish a bridge between clinicians and researchers from these diverse
fields.

The proposed Workshop will cover topics related with medical imaging
systems, such as:
=95 image acquisition
=95 signal processing
=95 image processing and analysis
=95 modelling and simulation
=95 computer aided diagnosis
=95 surgery, therapy, and treatment
=95 computational bioimaging and visualization =95 software development =
=95
virtual reality =95 telemedicine systems and their applications=20

[] D-TV
Scope:
In contrast to traditional TV DTV is a telecommunication system for
broadcasting and receiving moving pictures and sound by means of digital
signals. It uses digitally compressed modulation data, which requires
decoding by a specially designed television set or a standard receiver
(set-top box) as well as via PC-TV based on ADLS (VDSL). Digital
Television has several advantages regarding technically as well as
content and programme related aspects. One of the most significant is
the use of a smaller channel bandwidth.
This frees up space for more digital channels, other non-television
services such as pay-multimedia services and the generation of new
revenue models based on interactive advertisement and marketing
features. Furthermore there are special services such as multicasting
(more than one programme on the same channel), electronic programme
guides and interactivity providing a wider range of application.
Accordingly within the last year a growing up of specialised digital TV
channels (Special Interest Channels) has to be observed European wide.
This new growing up stream is mainly characterised by the phenomena of
merging television
(TV) and information technology (IT) know how, methods and techniques.
In this context the workshop targets to show up the development in both
directions: the technically aspects as well as the content and programme
issues. It provides a presentation and discussion platform for
exchanging experiences made within the establishment as well as the
maintenance of digital special interest channels. Main focus will be to
point out the interdependencies and the mutual influences of technically
streams and content respectively service related issues.
Topics:

    * Broadband Television
    * Interactive Television
    * IPTV - Web-TV
    * DVB-H, DVB-T, DVB-S, DVB-C
    * MHP & Interactive Television
    * Set-Top-Boxes
    * Full Digital Production Chain Management
    * Digital-Video-Journalism
    * DMB (Digital Multimedia Broadcasting)
    * FreeTV & PayTV
    * Interactive Video
    * Interactive Advertising Formats
    * Event Oriented Interview Formats
    * Event Driven Program Schemes & Formats
    * Mobile Content
    * Cross-Format Content & Knowledge Pooling
    * Cross-Media Content Production & Distribution
    * Indexing and Retrieval of Digital Content

Hi All,

If there are some unallocated memory that are heap
allocated by a DLL, are these released automatically
when the DLL is detached from the calling process or
do they remain in the heap as long as the application
calling the DLL is running? I have the same question
regarding global variables declared and used in a DLL.


I have a confusion in this area and I appreciate any
helpful reply.

Thank you in advance!

Best regards,

Metty

Too little information given!

If the image is in any known image format (GIF, JPEG, TIFF, PCX, BMP, ...)
then you need to locate a graphics library that contains code to read that
format.

If the data is in a raw binary file or stored as ASCII, then you have to
write your own code.

There is no way anyone can help you, if you don't take your time and
clearly specify your problem!

Hello Everyone,

Is anyone aware of how to read a greyscale image and convert it into a 2D
array of 256 by 256 in C++.

I would appreciate your contribution on this.

Kind regards
Benson.

Yes, strdup() is a nice function to know. If doing the allocation on
program startup, you can normally ignore to release the memory. If doing
it in a loop or not needing the results when your function ends, then you
should do free() on all pointers returned from strdup().

Try to google for "man strdup".

yep.. i will change 4096*256=1M part.  that is too big for saving serial
port info.

the function of strdup is equal to strlen() + malloc() + memcpy()?
so, i don't need to do memalloc for strSerialList as what i did, since
strdup() will do?
is this a correct understanding?

Now, you are preallocating 4096 bytes for 256 serial ports. That is 1MB of
memory. That is not something you want in production code.

My change with strdup() would have performed a strlen() + an optimum-sized
malloc() + memcpy() for any detected serial ports, i.e. it will end up
needing at the most a couple of hundred bytes of memory for the names.

Hi, Per,

  Thanks.  I asked my friend to see.  He gave me the suggestion.  The
RegEnumValue can recognize the com and USB->COM.  The problem solved now, I
got the correct result: COM1(com), COM7(usb->com).  In front of
RegEnumValue, add:
       dwName = sizeof(Name);
       dwSizeofPortName = sizeof(szPortName);
So the whole code is as follows (a bug in it: didn't release memalloc, but
doesn't influence the result here).

#include <windows.h>
#include <stdio.h>
#include <tchar.h>

int main(void)
{
    int z;
    char *strSerialList[256];
        for (z=0; z<=256; z++)
    {
        strSerialList[z] = (char*)malloc(4096*sizeof(char));
    }
    HKEY hKey;

    if( RegOpenKeyEx(HKEY_LOCAL_MACHINE,
                     TEXT("HARDWARE\\DEVICEMAP\\SERIALCOMM"),
                     0,
                     KEY_READ,
                     &hKey) != ERROR_SUCCESS)
    {
        return -1;
    }

     int i=0;
     CHAR Name[4096];
     UCHAR szPortName[4096];
     LONG Status;
     DWORD dwIndex = 0;
     DWORD dwName;
     DWORD dwSizeofPortName;
     DWORD Type;
     dwName = sizeof(Name);
     dwSizeofPortName = sizeof(szPortName);

     do
     {
       dwName = sizeof(Name);
       dwSizeofPortName = sizeof(szPortName);
       Status = RegEnumValue(hKey, dwIndex++, Name, &dwName, NULL, &Type,
                          szPortName, &dwSizeofPortName);
       printf("Name=%s,szPortName=%s  \n", Name, szPortName);
       if((Status == ERROR_SUCCESS) )
       {
          strcpy(strSerialList[i],(char*)szPortName);
          //strSerialList[i] = (char*) szPortName;
          printf("%s  ",strSerialList[i]);
          printf("i=%d,dwIndex=%d\n",i,dwIndex);
          i++;
       }
    } while((Status == ERROR_SUCCESS) );
    RegCloseKey(hKey);

    printf("\n\n");
    for(int j=0;j<i;j++)
    {
      printf("%s\n",strSerialList[j]);
    }

    return 0;
}

On an old test machine I have, the original code produces:
COM1
COM1
COM1
COM1
COM1
COM1

After adding strdup(), I get:
COM5
COM6
COM7
COM7
COM4
COM1

Are you sure that your change was correct, and that you remembered to
recompile?

One interesting thing here is that COM7 is printed twice, while my much
used COM3 is not enumerated.

The two COM7 seems to be a stupid M$ bug with an USB serial adapter :(

Hi, Per,

  for your second method, i modified like this.  i doesn't solve the
problem.  the result is the same as before.
  for the first method, i tried to change strSerialList[i] =
(char*)(szPortName); to strSerialList[i] = strdup((char*)(szPortName));, but
it seems doesn't work too.  :-(

Regards,
Jessica

     do
     {
       Status = RegEnumValue(hKey, dwIndex++, Name, &dwName, NULL, &Type,
                          szPortName, &dwSizeofPortName);
       if((Status == ERROR_SUCCESS) || (Status == ERROR_MORE_DATA))
       {
          strSerialList[i] = (char*)(szPortName);
          printf("%s\n",strSerialList[i]);
          i++;
       }
    } while((Status == ERROR_SUCCESS) || (Status == ERROR_MORE_DATA));
    RegCloseKey(hKey);

The test code is buggy. It uses the same buffer to retrieve the device
names, which means that the name will be overwritten.

A quicky (with a memory leak that doesn't matter here) is to do
strSerialList[i] = strdup((char*)szPortName);

Another alternative is to print the devices one-by-one directly when they
are found.

Name                      Type           Data
(Default)                  REG_SZ     (value not set)
\Device\Serial0        REG_SZ     COM1
\Device\U2SPORT1 REG_SZ     COM7

if i used on my computer, i can see:
COM1
COM1

when i used my .exe on my colleagues computer.
he has 2 serial port and 1 usb->serial.
but we can only see "COM4" for 3 times.

so at least, the code can recognize how many COM on computer, whatever real
com port or usb-com.
but cannot read right com port number.

Hi Jessica.

Can you, for start, list what is on "HARDWARE\\DEVICEMAP\\SERIALCOMM" in
your computer?

Regards
Rafael Menezes

is there anyone have the experience for writing code of getting the serial
port info from windows?
can u give me an sample code?

But I do have the answer. But I think you would have it too, if you look
at the header file where the WM_CLOSE message is defined. You will find a
huge number of other messages that you really want to know about, and a
lot of status and configuration flags.

Whenever you find an interesting message (or other symbol), it will then
be trivial to google or directly visit MSDN to get the _exact_ information
about when and how it is generated, or if there are version-specific
notices about it, i.e. a level of information that we can't take the time
to give you on this list.

In short: My answer is about methodology. Few things are as giving as
looking through the available header files. One hour with a couple of
header files will pop your head full with ideas what you can do. After
that, it is then trivial to flesh out the exact details about the
solutions.

You say that you have looked. My guess is that you forgot to look in the
header files, in which case my previous mail did specifically point you in
a very important direction. Life isn't always about getting explicit
answers. The best answers you can get on mailing lists or forums are not
explicit. The best answers you can get are the answers that solves a
number of future problems too. In this case: where to look.

In this case:
google on "minimize size event" should as first match have told you about
OnSizeChanged(). This might feel like a side track, but the word SIZE
should feel very important.

A bit closer look at the WM_SIZE message should have informed you that
wParam can be SIZE_MINIMIZED.

On the other hand:
Looking for WM_CLOSE in the include files would have noticed it in
winuser.h.

Searching for MINIMIZE in winuser.h would match:
#define WS_MINIMIZE     0x20000000
#define WS_MINIMIZEBOX  0x20000
#define SW_SHOWMINIMIZED 2
#define SW_MINIMIZE 6
#define SW_FORCEMINIMIZE 11
#define SM_CXMINIMIZED 57
#define SM_CYMINIMIZED 58
#define SPI_GETMINIMIZEDMETRICS 43
#define SPI_SETMINIMIZEDMETRICS 44
#define SIZE_MINIMIZED 1
#define SC_MINIMIZE 0xF020
#define HBMMENU_MBAR_MINIMIZE ((HBITMAP)3)
#define HBMMENU_MBAR_MINIMIZE_D ((HBITMAP)7)
#define HBMMENU_POPUP_MINIMIZE ((HBITMAP)11)
typedef struct tagMINIMIZEDMETRICS {
        UINT cbSize;
        int iWidth;
        int iHorzGap;
        int iVertGap;
        int iArrange;
} MINIMIZEDMETRICS,*LPMINIMIZEDMETRICS;

A quick scan at these matches should also give a very good idea how to
continue with google. They tell you such thing as how to configure a
window to show a minimuze button, to allow minimizing, to make it
minimized, to get the size of a minimized window, to catch the event when
it gets minimized etc...

Internet is large. To find something, you must develop a method how to
search and where to start searching. Only then can you quickly drill down
to the interesting parts.

You are of course free to consider my answers bad, but learning how to
search to be able to find the needed information in less than 5 minutes is
quite a lot better than to have to spend 5 minutes writing a question and
then have to wait hours or days for a possibly useful answer.

Have you spent any time on the MSDN site, reading up on the documentation
available there?

Have you bought yourslf a good book on Win32 programming?

Have you spent any time reading through the relevant header files - for
example looking for all constants starting with WM_?

You can define IDC_STATIC as:

#ifndef IDC_STATIC
#define IDC_STATIC (-1)

I test your code by Resource Workshop and it found not any errors. But in dev-cpp you have to include , 'cos ID_STATIC implemented in this file.

 I can't speak with any
certainty, but I'd say that the win95 os is too old to run any of the
more recent versions (post 2000). You'd need to look at the versions
that were out at the time. In all honesty it'd be much better to pick
up win98/2000/xp.

I have another problem with creating a dialog box using Win32.  I am trying to get text to appear on the dialog box.  Each time that I try to compile I am told that I am having a problem with 2 lines in the resource file.  
   
  //LINE 1:
   
  GROUPBOX      "Help for this program...",IDC_STATIC,7,7,225,52
   
  //LINE 2:

  I am told that there is a parse error in these lines.  I have windows.h included.  
   
  Could some one tell me what I am doing wrong here.  If needed, I will provide more of the program.
