I am using imdilate very frequently in my code, so speeding up this process would give me a huge performace benefit. Therefore I am trying to run it on the GPU.

se_c = ((X).^2+(Y).^2+(Z).^2<1);
C = imdilate(gpuArray(uint8(G)),gpuArray(se_c));

The following error message is issued: Error using morphopInputParser (line 48) Expected structuring element to be 2-D.

Is there a way to perform an image dilation of a 3D volume by a 3D structuring element using the GPU?

Is G binary? What are the typical dimensions of se_c? Of G?

No, this isn't possible unless you wish to write your own implementation. You are not the first to request this feature, it has been noted, and thanks for giving your feedback.

No need to say sorry. I was genuinly grateful for your response. I would have liked for the function to exist already, but now I know it's not available yet I can at least stop looking. Thanks!
