Effective estimation of target bits for rate control in video coding

This paper extends the steps for estimation of the number of target bits for the future frame during video encoding for an improved performance of the buffer which in turn reflects in a better reconstruction (peak signal-to-noise ratio). It includes two different approaches that consider the rate control module as a control system subjected to stability in terms of the target bits estimation error and thus yield benefits in terms of the buffer usage. It also proposes a possible way to take the work forward and formalize the methods to achieve optimal results.
