Apparently this assignment is to have you get practice in seeing how a sliding average window can reduce noise by replacing a pixel with the average of pixel values in a window around each pixel. Have you read this: http://www.mathworks.com/matlabcentral/answers/8626-how-do-i-get-help-on-homework-questions-on-matlab-answers If you run into trouble with your code that uses imfilter(), conv2(), or the brute force method, come back here with your code and images and we can give more hints.

IA, these days the recommended procedure for No Question + Homework, is to Close with an indication that a question needs to be asked.

If you close it then there's no way for him to respond, right? So he'd have to open a brand new (essentially duplicate, but better explained) question for an addition/correction/clarification of his first question. To me that seems worse than giving the poster an opportunity to fix the post.

Questions that are closed can be reopened by the original poster, including by editing the Question. This is different than Deletion; there is no way to respond to a Deleted post.
