Temporal filtering
I would like to ask a question which I could not find any answer for that in the internet. I was thinking about the Temporal filtering that I came up with this question that If it is possible to get average of some sequence of frames or not? if yes, what would be the benefit of doing this? Does it smooth the images? Is it a kind of temporal filtering? and....
Any explanation would be appreciated...
Could you please be a more specific of what you are thinking? Temporal analysis is used for a lot of things in computer vision. It can be used to evaluate motion, brightness and many other things. For example, intensity change in sequential frames can be used to detect areas where there is an adherent raindrop on the lens.
This could be an easy way of doing background substraction. If you have ideal and stable conditions, once this is done, everything that will appear in the image will be detected.
actually what I am going to do is noise reduction. I am using depth images and I want to work on motion blur. I do not know what would be the benefit of tracking 1 point in stream and what would be the result of getting average of a sequence of frames..somehow applying a kind of filtering algorithm into a sequence of frames. would it smooth the images?
