The java file is given below and saved as test.java

import dk.ange.octave.*;

import dk.ange.octave.type.*;

public class test {

public static void main(String[] args) {

    OctaveEngine octave = new OctaveEngineFactory().getScriptEngine();

    octave.put("input_name", new OctaveString("lena.jpg"));

    octave.eval("output_name = testimage(input_name);");

    String outputName = octave.get(OctaveString.class,

"output_name").getString();

    octave.close();

    System.out.println("Result is in " + outputName);

}

}

----------------------------------------------------------------------------------------------------

The octave file is as below and saved as testimage.m

function testimage(input_name)

im = imread(input_name);

imshow(im);

endfunction
