 \begin{quote}
 With stvid, I typically store 10 seconds worth of video frames, 100 frames at 10 \gls{Hz} frame rate or 250 frames at 25 \gls{Hz} frame rate into a so-called ``four frame''. Here, for each pixel of the initial 100 or 250 frames, the mean, standard deviation, maximum and argmax are stored, each as its own frame. Objects that move will stand out because they will have a high (max - mean) / standard deviation, which allows me to detect trails. Once a trail is detected, the argmax frame tells me the frame number and hence the motion of the trail, and using the timestamps of the individual 100 or 250 frames, I can reconstruct the pixel position as a function of time during the 10 second exposure, using only 4 frames instead of the 100 or 250 individual video frames.
