The global exposure videos have 1/4 the high-speed frame rate to match the sampling rate of our coded input.

Our result overcomes a large amount of blur and closely matches the ground truth. The 4x exposure has significant blur and has saturated highlights.
The blur in the 4x exposure video is also very evident in the adjusted view. The 1x exposure has significant noise in the dark regions. The denoised result has good quality in bright areas, but loses some details in the shadows, as can be seen in the close-ups below. Our result is sharp, has low noise, and is temporally consistent (even more so than the ground truth).

Our result | Ground truth |
In the first row, the apple stem is not visible in the denoised result due to over-smoothing of the low signal-to-noise ratio 1x exposure input. Our result still retains some of the detail of the stem. In the second row, the denoised result loses the detail of the dark line and blurs the petal significantly. Our result closey matches the ground truth.
