Hang on, measuring monitor refresh rate...

Explanation: In these images, we show the effect of different types of clamping during final frame generation.
Left: our method (see Section 3.2 in our paper).
Middle: clamping using the 3x3 area in the current subframe around the current pixel.
Right: clamping using all immediate neighbors (new and old) of the current pixel.
Note: At 60Hz, for example, our method looks worse (or similar) than the others, while at 240Hz, our image sequence looks substantially better.

Desired frame rate:
