Can we use this method to read images for training using FaceRecognizer class?

edit

here is the code

int train_ellen(vector<Mat>& images)
{

   Mat image=imread("ellen1.jpg", CV_LOAD_IMAGE_GRAYSCALE);


   if(image.empty)
   {images.push_back(image);

    labels.push_back(0);
   }

   else
   return 0;
   image=imread("ellen2.jpg", CV_LOAD_IMAGE_GRAYSCALE);
   if(image.data)
   {
images.push_back(image); 
labels.push_back(1);}
   else
   return 0;
   image=imread("ellen3.jpg", CV_LOAD_IMAGE_GRAYSCALE);
   if(image.data)
   {images.push_back(image); labels.push_back(2);}
   else
   return 0;
   for(int i=0; i < images.size(); i++)
   {

     resize(images[i],images[0],images[0].size(),1.0,1.0, INTER_NEAREST );
    }

    model->train(images, labels);
    return 1;
}

all three images are in the project folder.
