TV show CSI makes surveillance cooler, creeper. Kind of.

Recommended Posts

I watched a new episode of the TV show CSI [s15 E18] http://www.imdb.com/title/tt4145952/?ref_=ttep_ep18.

 

**Possible mild spoiler alert below** if you want to watch the episode.

 

In the above episode investigators use CCTV surveillance video to help get clues. The video clip they use captures two people talking in a greenhouse. Like many CCTV video there is no audio. The investigators use computer software and the plants leaf vibrations in the video to compile audio.

 

I thought this sounds all very possible, but how realistic? What I found really surprised me! Not only is it possible, but the 'audio' they 'created' in the episode wasn't just Hollywood glitter. Here's a link to the article, with video and audio too http://newsoffice.mit.edu/2014/algorithm-recovers-speech-from-vibrations-0804

 

Now mind you everything mentioned in that above link was done in controlled environments with one goal in mind. But still.

 

So, corn stalks have ears to listen, and leaves to tell!
