How to convert an image to Binary format using Java

Solution

Following is the program to convert an image to Binary format using Java.

import org.opencv.core.Core; 
import org.opencv.core.Mat; 

import org.opencv.imgcodecs.Imgcodecs; 
import org.opencv.imgproc.Imgproc;  

public class ConvertImageToBinary { 

   public static void main(String args[]) throws Exception { 

      //Loading the OpenCV core library  
      System.loadLibrary( Core.NATIVE_LIBRARY_NAME );
      String input = "C:/opencv/logo.jpg";
      
      //Reading the image 
      Mat src = Imgcodecs.imread(input); 

      //Creating the destination matrix 
      Mat dst = new Mat();     

      //Converting to binary image... 
      Imgproc.threshold(src, dst, 200, 500, Imgproc.THRESH_BINARY);          
      
      //Writing the image 
      Imgcodecs.imwrite("C:/opencv/imageToBinary.jpg", dst); 
      System.out.println("Converted to binary"); 
   }  

}
