Hello! I have a problem to make a detection, I need to locate multiple objects (people) was planning to use the algorithm of Viola and Jones extended version of Lienhart (included in OpenCV), can I make a massive detection (crowd, each one people) of objects with these algorithms? (I know it is mainly used for face detection) or exist another solution whithin OpenCV?
Can anyone help me? I no need a source code, just help me to choose an algorithm to do this o una solución

Possibly you may find better luck on the algorithms forum [^].

Are there any tutorials or guides on how to do this? If so, what/where are they? Thanks in advance.

i saw long ago an article here about a setup creator.
but there is was no such thing as the "run time" compilation of code unto an executable module.
the article was merely about an application that packages certain files in an exe by appending them to the end of a pre-existing exe resource and create an exe file that will in turn, ie at its execution, read what was attached to it and copy it to target directories specified in certain meta data.....good luck.

This question needs to use of OOP methodology in implementing a simple data encryption/decryption technique. The encryption technique will use the X-OR bitwise operator (^) and a random generator. Your program should first obtain a message up to 80 characters long from the user and then encrypt the message. It should then offer the user an option to either view the encrypted message or view the original message. The original message should be password protected – that is, the user should enter a correct password in order to view the original message. Set your password as “UECS1633”. The number of attempts to enter the password should be limited to three.
class will group all related variables and functions together. Must use the constructor and destructor functions also.constructor will be used to dynamically allocate memory and initialise class data members, while the class destructor will be used to free memory allocated by the constructor.
Sample output:
Enter a message to encrypt (up to 80 characters) => HELLO WORLD
Option:
1. View encrypted message
2. View original message
3. Exit
Enter option => 1
Message : îüêêïΣôïûêÇ
Display original message (y/n) => Y
Enter password => UECS1623
Invalid password!!! 2 attempts(s) left!!
Enter password => UECS1633
Message : HELLO WORLD
Message destroyed!!

no.
There are so many wrong answers in there...
1- University ? what courses do you have ?
2- Did you attend your classes ?
3- Did you do any exercises your classes set up for you ?
4- Did you asked questions to your teacher/teaching assistant if you did not understand the topics ?
5- ...

Electronic and communication engineering. M attending the classes now. Yup m doing the exercises but the topic that involve this question is not yet being thought. My lecturer ask me to try study first by own before he teach the topic. The due date is 2 weeks from yesterday. So m trying to study by own first...

Asking other people to complete your assignment does not count as studying.

Ok my friend... let me tried out first, if i stuck then only i refer back here... I get what you Mean. Thanks...

Good answer; anyone who needs help with their own work should get lots of help here. Only those too lazy to try get ignored.

First you don't use VC6 to compiling this code,you can guess the result that will call several Construction and Destruction,at last try to compiling it:
#include iostream.h
class A
{
public:
A()
{
cout<<"Constitution..."<<endl;
}
~A()
{
cout<<"Destruction...."<<endl;
}
};
A foo(A a)
{
return a;
}
int main(int argc, char* argv[])
{
A a;
foo(a);
A b = foo(a);
return 0;
}
why is 1 Counstruction and 5 Destruction ?
thanks for you reply !

Because your code only calls the default constructor once and several times the copy constructor (for which you didn't supply any specific function, so a default will be generated by the compiler).
If you supply a copy constructor the same way you provided a default constructor, you would see that both count matches.

Because default constructor is not the unique constructor, try:
#include <iostream>
using namespace std;
class A
{
public:
A()
{
cout<<"Construction..."<<endl;
}
A(const A & a){cout<<"Copy Construction..."<<endl;}
A & operator=(const A & a){cout<<"Assignment operator..."<<endl;}
~A()
{
cout<<"Destruction...."<<endl;
}
};
A foo(A a)
{
return a;
}
int main(int argc, char* argv[])
{
A a;
foo(a);
A b = foo(a);
return 0;
}
