Can any one tell me which algorithm is used for video compression in wsn? What is the compression rate?
Can you be a little bit more specific?
What is your color space, bpps, resolution, etc.
Thanks Christos,
Video resolution is fps= 15 and 1280x720. Or you can change it if you feel to change it.
Are you referring to a Wireless Sensor Network? If so, i don't believe there is a "fixed" way of doing video compression in such a network. I also think that the usual video compression codecs (e.g. mpeg) and methods (reduce bitrate, framerate, codec options etc.) would come into play.
Tha Gordon,
Yes it happens and its called wireless multimedia sensor network (WMSN). In this type of network video file must has to compressed before transmission. I want to know that which compression technique gives higher compression rate with good quality so that it can be used in WMSN.
Have you tried using the latest video compression standards like H.264 and H.265. You can try using them....
The compression techniques discussed in the post like mpeg, H.26X are all very complex to be implemented on resource constrained WSN nodes. Suggested techniques in literature include Wyner-Ziv encoding which is a kind of DVC.
