### Ideal two dimensional step function

I have asked the implementation of this part before. However, I am confused about the understanding the representation. So currently implementing a 5x5 kernel using the following ideal two-dimensional step function: http://oi62.tinypic.com/2z9l5xk.jpg My first question is: Is this ideal 2D step func...

### Re: Creating filter from an ideal 2D step function

@fmw42: Thank you so much :) I scanned through your post again, implemented and got just what I was looking for. Thanks again. Just one theoretical question, I was wondering how the values within an edge detection kernel be interpreted. For instance, in a simple edge detection matrix as this: [ -2 -...

### Re: Creating filter from an ideal 2D step function

You're misunderstanding the question. My is how to generate a 5x5 edge detection kernel from the edge detection?

### Creating filter from an ideal 2D step function

Hello everyone, How can one generate an edge detection kernel using the ideal 2D step function which is S(x,y)={(a for (xcosθ+ysinθ)<ρ OR a+h for (xcosθ+ysinθ)≥ρ)} which is geometrically represented as follows: http://oi60.tinypic.com/2ln7g47.jpg I actually need to generate a 5x5 kernel so that I ca...
