smoothing filter
Hi Everyone,
I have a question regarding smoothing an arbitrary signal. The signal is a entropy error rate which indicates the amount of information contained in dark and bright pixels in an image. The EER helps to find out the illumination in the scene.
The problem is the signal is constantly varying (coz of people moving in the scene), is there any way to smooth the signal using an adaptive filter or some kind of weighted average of previous N values and reduce the amount of variation.
I attached a Matlab plot of the signal.
Thanks
Snake
