Hi everyone. Can anyone please advise me on how I can select a rectangular region of interest with a hole in on an image, I wan't to do filtering on this area. So basically if you look at the attached image, I want to select the hatched region in the image and only filter that area with a motion blur filter.

Please don't ask me why, I just need a solution because i can't find anything on the web.

Given an image, you can make the inner region as zero. Apply the Gaussian (or your motion blur filter). Then, on this image, copy the elements that you made zero.

May I know that reason, so that I can suggest an appropriate alternative?
