title: openCV add 2 images in android
body: <p>I'm currently doing my final year project which is an android camera apps.</p>
  
  <p>I'm using openCV for my project. I want to add 2 images overlay each other. I realize in C++ has addWeighted function which can add 2 images. However this function can only be used in C++. openCV in JAVA don't have such function.</p>
  
  <p>I found out in JAVA have this function Imgproc.accumulate(src,dst)
  Does this function produce the same result as addWeighted in C++?</p>
