Thanks your great work. I hava some doubts want to ask you.

Figure 3 about the description of dynamic and static points on the ray is not understood. Specially the rays emanating from the dynamic points. Can you describe this in more detail?

what's the pixel-level temporal variance? Is it the variance of the color of each pixel over all frames within a video?
T is the length of the video frame?
$\bar{C}(\boldsymbol{r})=\frac{1}{T} \sum_{t=1}^{T} C(\boldsymbol{r}, t)$,Why is $\bar{C}(r,t)$ related to $C(r,t)$?
