Real time landmarks detection

[Siignature]

How to implementate the real time detection and position of the landmarks? I'm having problems with the landmarks, which are placed in incorrect positions. That's my code.

public void draw(Canvas canvas) {
        Paint paint = new Paint();
        paint.setColor(Color.GREEN);
        paint.setStyle(Paint.Style.STROKE);
        paint.setStrokeWidth(5);
        Face face = mFace;
        if (face == null) {
            return;
        }

        //Draws a bounding box around the face.
        float xOffset = scaleX(face.getWidth() / 2.0f);
        float yOffset = scaleY(face.getHeight() / 2.0f);
        float left = x - xOffset;
        float top = y - yOffset;
        float right = x + xOffset;
        float bottom = y + yOffset;
        canvas.drawRect(left, top, right, bottom, mBoxPaint);

        //Draws the landmarks
            for (Landmark landmark : face.getLandmarks()) {
                int cx = (int) (landmark.getPosition().x * 2);
                int cy = (int) (landmark.getPosition().y * 2);
                canvas.drawCircle(cx, cy, 10, paint);
            }

    }

The issue appears to be that you need to adjust for scaling between the original image size and the display size. Rather than multiplying by 2, you should multiply by this scale factor. See this example:

I posted a solution to this on issue #217. Hope it helps! :)
