title: Where to find MatofByte library in OpenCV , using in java
body: <p>I am trying to find the library for openCV.</p>
  
  <pre><code>import org.opencv.core.MatOfByte;  
  import org.opencv.core.MatOfRect; 
  </code></pre>
  
  <p>I found just by importing javaCV,  am not getting the above API.
  I need to download some other libraries as well.
  I am very new to openCV , so can any tell me how to get these libraries for importing in Java</p>
  
  <p>I did follow the link of jar , only change I did is I found a jar inside openCV extracted directory C:\Opencv\opencv\build\java, So I just imported that jar as library , it didn;t work. </p>
