Is there a name for a convolution that has the same size as the input?

Question

I have an input tensor of dimensions (C, H, W) and kernel with size (H, W).

It feels like there should be a name for this but I am unaware and can't get Google or ChatGPT to show it to me. Is there a name for this?

Answer 1

Turns out I am stupid, this is just a fully connected layer.

ChatGPT had me confused as to how convolutions work but yeah, it is in fact a different kernel for each input channel in every filter, making this "convolution" have one weight for every connection from an input neuron to an output neuron, which is effectively a fully connected layer in disguise.
