Java | How to convert color image into grayscale image

You must have heard of grayscale image and may have even used the process in image processing software like Photoshop to get a grayscale image. In this video we will learn to convert a color image into grayscale image using Java programming language.

In this video I'm using BlueJ. You can use any other editor/IDE like Notepad++, NetBeans, Eclipse etc.

You can download the Image Processing Project code from my GitHub repository

This video gives you a glimpse of operations you can perform on image using Java. More operations are there in my GitHub repository like thresholding of image, converting color image to grayscale image, image filtering like median filter, mean filter etc.

Have fun coding :-)

Can you please help me a little? I tried to add a button to your image viewer, and then add an action to that button, so when I click the button it should make the image grayscale. For some reason I can't make it work. I cannot add IOException to buttons that i added with JFrame also i have no idea how can i get the pixels' information from the picture i have opened.
