Hi, we've learned at school that,
in face detection the color of lips can give a clue to find the face
if you find the position of lips you can use the ratio of the face
in human face there's a symmetry and all parts of the face has an arithmetical ratio to another, this may help you,
but it may not be able to use coz women use lipstick,
may be u can use horizontal and vertical histogram together (intersection of them)
or you may use dynamic quantization to find similar colors together as a label
(i mean labelization, like Photoshop's technique, you touch to a pizel then it draws a closed area)
i think the old replyers are right this is a technical research not a part of code
you must search for the academic researches

First ‘Maximilien’ gave you a good place to start, second if you need to ask this question then you may be in over your head. Look for code that can take an image apart. If you can not break it down, then you are in trouble. If you can, than even a pimple can tell you what you need to know.
Keep searching!

Is this correct code. which I am posting here above. Please let me know?

Why +1 ?

No.
if (pbyCmd) delete [] pbyCmd;

Thanks.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif) After long time we met .
Ok If i said
pbyCmd = new BYTE[1];
then?
delete pbyCmd;
delete[] pbyCmd;

Checking for NULL while deleting pointers feels unnecessary. There is no harm deleting NULL pointers.
And if its dangled/uninitialized pointer, that will cause problem any way.

Whenever I stumble across a project in Unicode, I can never
compile it. Its always looking for other files.
Is there any easy way to compile a project in Unicode? Something
obvious Im missing.
Any response any one can give me will be greatly appreciated.
Sincerely,
Danielle Brina

What files is it looking for ? You should have all the files you need, I'd have thought.

There is a sample project here:
http://www.codeproject.com/listctrl/xlistctrl.asp
If I download and compile it, I get errors. It just seems like
every Unicode project I download compiles with errors. There is
always something missing. It must be me.

I guarantee it is not you! The files are there or they are not, ‘Hans Dietrich’ is one of the best at CP. So go to MS and make sure you are up to date. If you are using VC6 or above, then you should not be having these problems, if you do then there is a flaw in the code or (god fobbed) your understanding.

Hi all,
can anybody please tell me what is the difference between window socket and CSocket class
thanks in advance

The latter is a VC++ wrapper around the former.

Hi to all,
1) What is use of Abstract Class? What it's advantage over normal Class?
2) As I know,
=>Steps in TCP Server are,
(1).Create TCP Socket (using SOCK_STREAM), (2).Bind to a Port, (3).Listen, (4).Accept a connection (from Client), (5).Send & Receive Data
=>Steps in TCP Client are,
(1).Create TCP Socket (using SOCK_STREAM), (2).Connect to a Socket(TCP Server), (3).Send & Receive Data
=>Steps in UDP Client are,
(1).Create UDP Socket (using SOCK_DGRAM), (3).Send Data to a UDP Socket; Receive Data from a UDP Socket
Am I right?
What are the step to be done in UDP Server?
When I searched it in Google, I found that UDP Socket can use 'Connect()' ! But how it is possible if UDP is Connectonless?
3) In VC6, how to get Pixels of a JPEG Image? How to show image using it's pixels on the Dialog?

It can define an interface with no implimentation. C# has interfaces, C++ does not, this is one way to get them.

Use GDI+ ( this involves finding a PSDK that works with VC6 ), or use a library like CXImage or Paintlib. Or, get a decent C++ compiler

1) An abstract class has at least one pure virtual function. That means that an object can't be
created of that class' type. It can only be used as a base class. This defines virtual methods
for a class heirarchy while forcing derived class(es) to provide an implementation. I guess
one advantage is that using a pointer/reference to an abstract type, you are assured that any pure
virtual functions have a derived class implementation.
2) connect() when used on a UDP socket just sets the default destination address so if you
use send(), the datagram will be sent to the "connected" address. If you don't use connect then
you have to use sendto() to send a datagram. If you do use connect() then you can use send()
and/or sendto().
3) The JPEG compressed data needs to be uncompressed to get pixel data suitable for displaying.
