OpenCV 3.0 Computer Vision with Java

A Java OpenCV simple application

It's time to create a simple application that will show that we can now compile and execute Java code with OpenCV. Create a new Java class containing a Main method and paste the code given as follows. It simply creates a 5 x 10 OpenCV matrix, sets some of its rows and columns, and prints the result to the standard output.

Make sure you load the correct dynamic link libraries through a call to System.loadlibrary("opencv_java300"). Since, you might want to change the library version later, a better approach would be to use the Core.NATIVE_LIBARAY_NAME constant, which will output the correct library name. You can also find this file in the code repository for chapter1 of this book, under ant/src.
