问题
I am working on this paper. I have to apply particle filtering on it in place of markov filter. This paper is all about video anomaly. I have to implement particle filter on video. For this purpose, I need to draw samples from proposed distribution. As given that:
To initialize that initial sample we have to take value from this
To extract samples x from proposed distribution q, we require this equation
We also need to develop this x which include process noise "v" and non-linear "f"
These general things are cleared. But what should be "q~proposed distribution" so I can extract samples from it. As I do not have any idea about what is my proposed distribution. And I cannot understand how do I extract samples from it. And on the basis of video what should be this proposed distribution.
This link I was following. In this link they apply particle filter on different equations. But I have to apply it on a video. And this is another LINK, which provides general overview. I have came through many links, but I cannot resolve my issue.
