you are totally misreading it. the frame is the individual image, a stream of which creates a video, generally at 24 or 30 FRAMES PER SECOND.What this algorithm does is rather than try amplification and noise reduction in a single frame, then move onto the next frame, etc, this analyzes preceding and following frames to try and better predict which frames need amplification to create a video with more detail.now personally, after having seen the sample videos, I think the variance in what should be "solid" areas of the picture makes the video annoying to watch in the extreme.
thanks, but I think you misread my question actually. I'm not talking about the algorithm, or at least the quote isn't, and perhaps use of the word 'frame' in the context of the beetle brain rather than the video is confusing.I'm referring to the capability of the beetle's brain that the algorithm is trying to replicate, i.e. the spatio-temporal smoothing capability that 'inspired' the algorithm. as the name suggests, it is smoothing over 'space' AND 'time'. My understanding of quantum mechanics is that one could observe a photon in either space (position or orientation at a given moment) OR time (change in position or orientation), but not both. But the dung beetle brain apparently does.
Your understanding is incorrect. One can measure a photon or particle's position in space and time. What matters is the precision to which you can measure it. You must sacrifice precision of one to measure the other more precisely.In the case of the dung beetle, or your video camera, the measurements being taken aren't all that precise to begin with. A pixel or rod/cone is pretty large, and the period of time in which photons can hit them when you're taking around 60 measurements a second is enormous on the quantum scale.So the uncertianty principle is of no concern here.

nothing like the smell of dung beetles in the morning
