I am trying to find the library for openCV.

import org.opencv.core.MatOfByte;  
import org.opencv.core.MatOfRect;

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

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.

Have you imported those core libraries into the build path?

Check http://docs.opencv.org/doc/tutorials/introduction/desktop_java/java_dev_intro.html and

http://docs.opencv.org/doc/tutorials/introduction/windows_visual_studio_Opencv/windows_visual_studio_Opencv.html ,in case you are using visual studio.

Those classes are only available in OpenCV for Java (http://opencv.org), which is a totally different wrapper than JavaCV (https://code.google.com/p/javacv/).

You need to use the classes corresponding to the libraries you are linking.
