Calculation of Bd-rate

Believe that a lot of contact video coding friends in the relevant literature, always see the paper in the test given an important parameter bd-rate, may have been questioned, this bd-rate what is a thing? Can refer to this proposal http://download.csdn.net/detail/hevc_cjl/4927493

To put it simply, this bd-rate calculates the mean value of the difference between the two rd curves corresponding to the two algorithms, specifically by fitting the curves of several (typically 4) points in the test, then making the difference, and finally averaging the values. The computational process is still relatively complex, and the following proposal gives a way to calculate using Excel http://download.csdn.net/detail/hevc_cjl/4927499
