Monochrome grayscale image, get the intensity of a pixel

Question

I\'m attempting to derive an intensity value for a particular pixel in a monochrome \"grayscale\" image. I have some pseudocode, but thus far I\'ve been unable to implement some

Maybe this will help you:

http://docs.oracle.com/javase/7/docs/api/java/awt/image/BufferedImage.html

http://docs.oracle.com/javase/7/docs/api/javax/imageio/ImageIO.html

BufferedImage img = ImageIO.read(new File("filePath.png"));

int sRbgColor = img.getRGB(int x, int y);

Color c = new Color(sRbgColor);
int red = c.getRed();
int green = c.getGreen();
int blue = c.getBlue();

If it's monochrome, then red green and blue should be equal.
