Image Smoothing - Opening

Introduction

Image smoothing can be performed by application of morphological operations in ordered fashion.

• First erode image
• Then dilate it

Image gets smoothed by removing bright pixels.

Size of structuring element i.e. order of kernel to be used Erosion & Dilation, can be specified, which will control extent of smoothing.

Usage

• Put this code snippet into Java source file.

import in.itzmeanjan.filterit.ImportExportImage;
import in.itzmeanjan.filterit.smoothing.Opening;

public class Main{

	public static void main(String [] args){
		System.out.println(
            ImportExportImage.exportImage(
                new Opening().smooth("eye.jpg", 5, 5), 
                "opened.jpg"));
	}

}

• Compile & run, make sure you've added in.itzmeanjan.filterit.jar as your project dependency.
