I need the MATLAB code for a rectangular moving average window for an image that is in my computer. It is a part of the my self learning :)

This is a part of your learning, but you want us to post the required code?! I assume, "learning" implies, that you try it at least by your own.

NO dude. I meant I need to figure out how to do the whole process in MATLAB. To know the format.

在 MATLAB Online 中打开

Try this:

blurredImage = conv2(yourImage, ones(windowSize));

You'll get a few errors if you have a uint8 image or color image, but they should be easy to figure out. Let me know if you can't.

So, if have a grayscale image to which i have to apply the rectangular moving average window filter,with variable width of say 0,5,10 etc, normalizing total integral to 1, how should i approach the problem right from basic. I ask this question since I am new to MATLAB totally, and I am required to do this as a part of hobby project. So, if you can give me a detailed explaination, it would be greatly appreciated :) Thank you.
