Image Processing 1- OpenCV, C++ - Color to Greyscale Conversion

Soln 1:

#include "stdafx.h"
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
#include <opencv/cv.h>

using namespace cv;
using namespace std;

int main()
{
    //Read Color Image
    Mat im_rgb = imread("C:/Users/kvemishe/Documents/Vision/images/kitten.jpg");

    //waitKey is important for image display; 0 means wait forever
    imshow("Kitten",im_rgb);
    waitKey(0);

    //Convert Color to GrayScale
    Mat img_grey;
    cvtColor(im_rgb,img_grey,CV_BGR2GRAY);

    //Write Greyscale to file location
    imwrite("C:/Users/kvemishe/Documents/Vision/images/kittengrey.jpg",img_grey);
