splitting image results in unhandled exception error

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");
while(1)
{
    cam>>image;
split(image,rgb);
    Bch = rgb[0];
    Gch = rgb[1];
    Rch = rgb[2];

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.

thanks

Although this is an old issue I would like to share the solution that worked for me. Instead of vector<Mat> rgb(3); I used Mat channels[3];. I realized there is something wrong with using vector when I was not able to use split even on an image loaded with imread. Unfortunately, I cannot explain why this change works, but if someone can that would be great.

It sounds as if split expects there to be three instances of Mat in the rgb vector. But you have only prepared it to hold three items - it is actually empty.

Try adding three items to the vector and run again.
