I am a beginner to opencv.
I have a C++ app that uses OpenCV. Currently i am statically linking the OpenCV libs into my app. This is adding an extra overhead of 6+ MB.
i would like to remove some of the features that i am not using in OpenCV. The features am using are,
Capture frames from Webcam.
Face detection.
Image formats (JPEG, PNG).
Image rotation & resizing.
Is it possible to remove other features and trim down the libs?
My C++ app is developed in Visual Studio 2012.

The above code is all I have so far. I got confused when I got to the part where my book on C tells me I need to use the cvCalcOpticalFlowFarneback() function to compare 2 consecutive images from the webcam and create the optical flow, and then measure movement between the frames to detect whether or not a person is moving through the room. How to do this, and the OpenCV wiki wasn't very descriptive on how to set it up for beginners. Honestly, the parameters just confused me and I didn't see a return value listed, or how you would get data from it.
I am trying to switch between 2 states, and the event that determines which state i am in is based on the key i've pressed. So in this case i want the webcam to start automatically, and when key is pressed it then turns it off. The way I've done it is like this :
bool webcam_on() {
int c = 0;
VideoCapture cap(0);
if ( !cap.isOpened() ) // if not success, exit program
[Code] .....
The problem with this method is that cin.get() blocks the video stream.. I wanted something that the webcam turned on until i press some key, which would trigger the release.. How can this be done?
I have a text file which consist of several values. These values represent distance from origin to any point in the triangle. How can I create histogram from these values? Is there any functions in OpenCV which can create histogram from these values?
Below my sample values are given:

I am currently planning on splitting my image into 3 channels so i can get the RGB values of an image to plot a scatter graph so i can model is using a normal distribtion calculating the covariance matrix, mean, etc. then calculate distance between the background points and the actual image to segment the image.
Now in my first task, i have wrote the following code.
VideoCapture cam(0);
//int id=0;
Mat image, Rch,Gch,Bch;
vector<Mat> rgb(3); //RGB is a vector of 3 matrices
namedWindow("window");
[Code] ....
but as soon as it reaches the split function, i step through it, it causes a unhandled exception error. access violation writing location 0xfeeefeee.
I am still new to opencv, so am not used to dealing with unhandled exception error.
I tried adding items into the vector still error, either via push_back or general assignment i.e. rgb[0] = Rch or Bch still error.

I am having problems at the end of the program with the do-while loop to restart the program and the validation.

so my homework assignment is to make a program of which removes any notes in a program file.
for example, you run my program it will ask for a filename, when entered it opens the file, copies everything in it and removes any double forward slashes (//) and anything after that up to the new line character ( ) and anything between /* and */ including the /* and */.
i created the entire program and it removed the // and anything after that up to the new line character but will not remove anything after the first / when it finds a /*. This includes the */ at the end of the comment.
the section of code that removes the comments is
//this loop removes all notes
for(i=0;i<buf.st_size;i++) {
if((filecontent[i]=='/')&&(filecontent[i+1]=='/'))//removes notes using //
{
for(i=i;filecontent[i]!='
';i++)
filecontent[i]=' ';}
[Code]....
i know that the section that removes the multi line comments would not remove the final */ at the end if it did work, i was planning to fix that later once it removed the comment.

My program is ruuning perfectly only problem is that i must transform it to program uses class, class student . Am very beginer in using classes, so far i do very easy programs using classes.
so far i have this
#include "stdafx.h"
#include "student.h"
student::student(vector<STUDENT> studenti) {
vStudent=studenti;
[Code] ....
I try to make it but its too difficult for me. in that student.h and student .cpp is 50 errors..
Here is my code
#include "stdafx.h"
#include <string>
#include <vector>
#include <sstream>
#include <iostream>
#include <fstream>

I want to make a program which can run in another program. My program have structures flowing:

I've been working on a small SDL program and decided I wanted to throw the program on to a disc so I could show some people what I'm working on. However, when I try to run the executable, the program crashes and under more details it says that the fault lies on SDL2_ttf.dll .
Why does this program work inside of VS2012e and not in windows?
What I did :
Set the program to release, hit f6, and then tried to run the executable from windows.
Additional information :
Compiler : Visual Studio 2012 express
O/S : Windows 7 64bit
SDL lib : 32 bit version
For instance Code: int counter;
counter =0;
FILE *pfile;
pfile= fopen("g:myprog.txt" "w");
while (counter >100)
{ fprintf (case counter{something})}; how do I do this?
Cannot divide the real output of the AVERAGE.:
Code:
#include<stdio.h>
#include<conio.h>
struct student
{
char Name[50];
[Code]....
how to get the output of this program.. I'm not completely lost but I need it in the simplest terms.
Code:

is there anyway to have a program where it ask for three numbers and you shows which which number is the largest and which is the smallest, e.g.
Enter 1st number: 30
Enter 2nd number: 10
Enter 3rd number: 30
Largest = 30
Smallest = 10
I am working on a program to compute the natural log of numbers using several different methods, but I am having a couple of issues. Firstly, when using Borchardt's Algorithm I almost always end up with nan as a result, even though I am pretty sure I got the formula correct. Also, in my lnDemo.c file It doesnt give me the correct answer and the second time around I get a segmentation fault.
Code:
//myLog.h-------------------------------------------------------
//These functions will compute or aproximate the natural log of a number
//This method will use a formula to compute it
int lnFormula(double x, int m,double *result);
