We can display the image perfectly fine through a simple gui. The problem is with our bufferedImageToMat(Mat img) function:

	public static Mat bufferedImageToMat(BufferedImage i){
		byte[] pixels = ((DataBufferByte) i.getRaster().getDataBuffer()).getData();
		Mat img = new Mat(i.getWidth(),i.getHeight(), CvType.CV_8UC3);
		img.put(0, 0, pixels);

		return img;
	}

However this is exactly the same as many of the online examples, if anyone has any ideas that would be appreciated. Also, what does everyone think about using OpenCV on the roboRio

This seems odd. Can you provide some screenshots?
