Hello Everyone,
I need RMS algorithm for video in Matlab. Has anyone it?
Hello Everyone,
I need RMS algorithm for video in Matlab. Has anyone it?
RMS is not difficult. I don't code in Matlab anymore but can give you the algorithm and then you can code it. Or just find one online?
I have this algorithm but i don't know how can use for video
RMS looks like the following:
Let's take a simple signal:
X = [0, 1, 2, 3, 4, 5]
Then it would be the following:
rms(x) = sqrt(0^2 + ....../n
)
Where n
is the number of samples.
In other words, take the squared mean of the dataset, from this, find the square root. Simples
You haven't given a clear indication to what exactly you want to use with RMS for but I can make the assumtion that you need to carry out some kind of thresholding, if this is the case then:
1) Split your signal into segments
2) Calculate the RMS for each of these segments.
Here is the code written in MATLAB
function rms = quadraticMean(list)
rms = sqrt(mean(list.^2));
end
