How Can I Remove Flickering Background in a Video? I have a black and white video taken with a high speed camera and I notice a background flickering coming from my LED light.  The images alternate from dim to bright and it makes the videos quite disorienting.

Besides getting a different light, is there any post-proccessing that can be done to remove this effect?  Possibly something from the image processing toolbox in matlab, or something in imageJ would be helpful as well.

I have already acquired quite a few videos and would hate to have to repeat everything all over again so any help would be greatly appreciated.

thanks!
For those classic Video Processing operations there is nothing better than the Plug In's of AviSynth.

Specifically for De Flickering look at:


LMFlicker.
ReduceFlicker.
DeFlicker.


The source code of each is available so you can get inspiration from them.

All of them basically works on smoothing the Luma Data along the temporal dimension.
