I have image in csv file and i want to load it in my program. I found that I can load image from cvs like this:

```
CvMLData mlData;
mlData.read_csv(argv[1]);
const CvMat* tmp = mlData.get_values();
cv::Mat img(tmp, true),img1;

img.convertTo(img, CV_8UC3);
cv::namedWindow("img");
cv::imshow("img", img);

```

I have RGB picture in that file but I got grey picture... Can somebody explain me how to load color image or how can I modify this code to get color image?
Thanks!
