comparison of temporal denoisers

[Katie Boundary]

I have a couple of temporal denoisers but a lot of them seem to operate on the basis of "last denoised frame (which may contain traces of 20 previous denoised frames)" rather than "previous raw frame and next raw frame". This methodology leads to a lot of ghosting. Any suggestions for good "previous raw frame and next raw frame" denoisers?

Which denoisers operate like that?
