Description

I went through the somewhat older issues and found #427 to be of my interest to implement.

This PR creates three modes in which to treat the border pixels in a Convolution operation. These modes are:

  1. Clamp (the current implementation)
  2. Wrap
  3. Mirror

I don't like the None name proposal in the original issue, as I feel you have to make a choice about your borders. And with the name Clamp we make clear what operation we perform.

Please advise on how to expose this in the public Convolution API's.
For example, please specify your preference on questions like:

  • On which class to expose the BorderWrappingMode property ?
  • Specify the modes of X and Y directions separately? Or just a single property for both directions?
  • Switch the default from Clamp to Mirror ?
  • Add this functionality to Resize also ?

Other feedback or suggestion are also welcome !

Oh wow! This is a pleasant surprise! I never looked at this after refactoring convolution so thought the changes would still be really viral.

Will do. We’re currently investigating some access violation issues #2075 that we need to resolve before we merge any more code.
