Think of it like this: you have a drawing, that's the image, and you have a stencil, that's the filter. You take that stencil and pass that stencil over that drawing that you have, and as you do that you will see that some parts of the drawing become more visible than others as you do that, right? And that process of sliding that stencil across this drawing is essentially the process of convolution. Now that we've explained what a filter is and introduced the concept of convolution, let's use an analogy of written language to understand the relationship between the filters
