Prueba con esto. Conviertes tu Image a Buffered Image

/**
* Converts a given Image into a BufferedImage
*
* @param img The Image to be converted
* @return The converted BufferedImage
*/
public static BufferedImage toBufferedImage(Image img)
{
if (img instanceof BufferedImage)
{
return (BufferedImage) img;
}

// Create a buffered image with transparency
BufferedImage bimage = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_ARGB);

// Draw the image on to the buffered image
Graphics2D bGr = bimage.createGraphics();
bGr.drawImage(img, 0, 0, null);
bGr.dispose();

// Return the buffered image
return bimage;
}

y ya tienes la bufferedImage sobre la que aplicar el resto del código.
