What is the meaning of spatial and temporal ?

I hav seen these name a lot in denoisers but what that means

[10L23r]

general definitions:
spatial: that which is occuring in a single frame
temporal: that which occurs in a specific localized region of multiple frames

examples:
so temporal noise may be random flickering in the corner of the screen, and spatial may be compression artifacts near text...

hi, i think i can more or less understand how spatial/temporal noises are like, but i've also heard something like spatial/temporal motion, which i dont quite understand. if there's motion, isnt it always have multiple frames involved? how's spatial motion like?

A spatial denoiser doesn't look at other frames.

A temporal denoiser does.

That's about it.

[GasKid]

or is it spatial/temporal motion vectors? maybe i am confusing something.

Maybe you heard it wrong. Do you have a link?He's thinking of B-frame direct modes.
