title: Live Camera Streaming in Android
body: <p>I know how to give effect of Pencil Sketch to image but my question is different from this.</p>
  
  <p>I found <strong>Pencil Camera</strong> app on <a href="https://play.google.com/store/apps/details?id=com.ljezny.pencilcamera" rel="nofollow noreferrer">Play Store</a> which is using Live Camera Streaming in its Application.</p>
  
  <p><img src="https://i.stack.imgur.com/7OotU.jpg" alt="enter image description here"></p>
  
  <p>After showing image you already know what my question will be. </p>
  
  <p><strong>Question</strong> : How can I achieve this?</p>
  
  <p>I know about <strong>Camera Color Effects</strong> but it has not such option. Will <strong>OpenCV</strong> do this?</p>
