Point filtering?? 1. The problem statement, all variables and given/known data Remove the coherent noise from the X image by first implementing a notch filter, and then revising this to remove the noise through point filtering 3. The attempt at a solution My problem is that I'm not too sure about what point filtering means. I've done the first bit of the question in that I've applied the notch filter, but I'm not too sure what it means by remove the noise through point filtering. I thought that maybe point filtering referred to something like a median filter or an average filter but I'm not entirely sure. Can anyone help??
