Features2d.drawKeypoints(mKeyPoints_0, mKeyPoints_0, outImage, Scalar(200,0,0), Features2d.DRAW_RICH_KEYPOINTS); should do it, like @berak said. I do not think the new is actually needed.

^^ java needs it.

(there's no way to create something on the 'stack' there, so new Point(), new Scalar() new Mat(), etc)

@steven i think @berak is right, i tried to use Scalar(..) without the new operator and it is not allowed
