Hi,
I've been given a project which receive images from a webcam on the white plane and count the number of black balls on the white plane and find the position of the balls on the plane.First it receives images from web cam and transform them into a 8 bit greyscale mode and apply several image processing filters on the image.How can I do it and which webcam should I use?
Note:I must use Visual C++ 6.0

How can I convert the image taken by webcam to 8 bit grayscale format?

I'm not sure whether this is a COM or simply a C++ library query.
Basicaly, i've got a program that needs to read the current appearance data of windows. But i can't find where to find the information from ANYWHERE.
I need the following values:
(For NT)
* Title Bar Size
* Title Bar Colour
* Title Bar Text Size
* Title Bar Text Colour
* Window Border Size
* Window Border Colour
For both Active and Inactive windows.
I don't really need details on how to do both, just what to do to get them for NT.
(For XP)
* The shape of windows, i.e. whether windows have the rounded corner, and if so, how I can get the graphics map for them. I can set this manualy, but it isn't dynamicaly changing depending on user settings.
* Besides that, I really need similar information as above,
Text Size, Text Colour and Title Bar Size.
XP doesn't seem to have resizable windows borders, so I don't think I need that.
Any pointers into what DLL + Method I should be using would be a great help, as I've trawled through MSDN looking for windows appearance and display API libraries and found squat.
Cheers
Cata
[Edit: I think I found what I'm looking for in GetSystemMetrics + GetSystemColor. If anyone can tell me if this works for both NT and XP, it would be really helpful.
I still haven't solved the graphics path for cropped window shapes, so if anyone know what to do about that, I would be greatful.]

There might be an easier way I don't know about, but check out ::GetWindowRgn() for window shapes.

Windows shape seems to be theme related, so i'm going to invenstigage the windows theme DLL. If it's disabled, then the windows will be square by default, but some custom theme styles use square as well.
Additionaly, I've got a problem with finding out information on the font and colour of text for windows caption bars.
Do you know where I could find out about this?
Cheers

Yes. ::GetWindowRgn() takes that into account.

::GetSysColor(COLOR_CAPTIONTEXT) and ::GetSysColor(COLOR_INACTIVECAPTIONTEXT) might do the trick for the color part.
Check ::GetStockObject() for the font part. I really don't know if it's covered here, but it might be worth the check anyway.

I`m doing datawarehouse task for my degree. You`re doing a datamining project? CAn you tell me more about it? I have done it myself using decision tree. But I think it has the wrong algorithm.

hi,
i am doing datamining in Health care area.so u r using decision trees.why don't u use microsoft analysis services.
that component itself providing decision tree algorithm.
Here i am using analysis services that comes with sql server2000.
where u from ?.what kind of project u are working ?.if u specify the problem domain,may be i can share my little exprience with you.

Well i haven`t known sql server before. So I build it using my own application. I am studying sql server now.
From indonesia, maybe a place where you have never imagine.
I`m doing a project for my degree, about implementation of datawarehouse at a company. Thanks for the help again. Maybe if i have another problem, i`ll contact you

Abstract
Data classification is an important problem in data mining. The traditional classification algorithms based on decision trees have been widely used due to their fast model construction and good model understandability. However, the existing decision tree algorithms need to recursively partition dataset into subsets according to some splitting criteria i.e. they still have to repeatedly compute the records belonging to a node (called F-sets) and then compute the splits for the node. For large data sets, this requires multiple passes of original dataset and therefore is often infeasible in many applications. In this paper we present a new approach to constructing decision trees using pre-computed data cube. We use statistics trees to compute the data cube and then build a decision tree on top of it. Mining on aggregated data stored in data cube will be much more efficient than directly mining on flat data files or relational databases. Since data cube server is usually a required component in an analytical system for answering OLAP queries, we essentially provide “free” classification by eliminating the dominant I/O overhead of scanning the massive original data set. Our new algorithm generates trees of the same prediction accuracy as existing decision tree algorithms such as SPRINT and RainForest but improves performance significantly. In this paper we also give a system architecture that integrates DBMS, OLAP, and data mining seamlessly.

This process involves quite a lot of time. During this process, i want to implement a progress bar, showing the status of the process. How do i do tht.
Can someone, please help me on this. I thank in advance.
cheers

You can have a simple dialog loaded from the MDI - It would be only displaying the progress bar. The value of the progress bar can be set from the parent MDI.
* Artificial intelligence is no match for natural stupidity! *

I tried that. But that doesn't happen in parallel. Only after the progress completes, my process of loading the file starts.

Hi ,
I want to add a menu to dialog bar, not dialog box. For dialog bar, the menu property is disabled.Is there a way to to this?
My Main aim is to have a seperate menu for MDIChild window-form view. So I intend to attach a menu to dailobar and add this dialog bar to form view. I want to use a dialog bar instead of a dialog here.The problem with dialog box is when the focus is on the view, the dialog menu appears to be disabled i.e grayed and vice versa. Or cau you please suggest how to make the dailog appear to be eanbled irrespective of focus
Thanks
madhavi.
