Now we attempt to model the number of cells in the scene-change frames. It is clear that the frames that start a scene will have stochastically more cells than other frames because most of the picture has to be constructed afresh. Different models will be needed for the scene-change frames than for the intrascene frames. Plots of the autocorrelation function showed no correlation among frame sizes, so obtaining the distribution is the main modeling issue. The distributions we use are on the interval 0; I . The minimum number of cells in a scene-change frame is a few thousand, so we shifted the data by subtracting the

smallest value. In other words, we model the amount larger than the minimum value in the data. Figure 12.9 shows how the empirical values of g1 and g3 compare to the curves for the Gamma and Weibull distributions. Except for fysics and football, the data are far from the theoretical curves. Since the third moment has a large sampling error for long-tailed distributions [18, p. 26], the deviation from the theoretical curves may be due to sampling error. Based on Q-Q plots, two of the sequences (Isaura 1 and Isaura 2) had good Weibull ts, and two (dutch and star wars) had good gamma ts. The lognormal distribution ts the lm data well. We could not t a model to the other sequences. We conclude that a known distribution may not always be a good t to the number of cells in a scene-change frame, and that the same distribution is unlikely to be a good t to all sequences. 12.3.4 Intrascene Frames

A close look at the bit-rate plot in Fig. 12.6 revealed that the effect of a scene change appears to last for two frames; the rst frame after the scene change is also extra large. This was also observed by Ramamurthy and Sengupta [26] by looking at Fig. 12 in Verbiest and Pinnoo [30]. Since our data were produced by the same codec as the data in Verbiest and Pinnoo [30], this is not surprising. We examined lm, Isaura 1, and Isaura 2 and found that linear regression provided a good model for the

number of cells in the rst frame after a scene change. Letting Zn be the number of cells in the nth scene-change frame, and Yn be the number of cells in the succeeding frame, we have Yn a bZn En ; 12:7

where the En are independent and identically distributed normal random variables with mean zero. For the rest of the intrascene frames, the autocorrelation function and the distribution are important. Figure 13 in Verbiest and Pannoo [30] shows an autocorrelation function of a TV scene; it does not decline geometrically to zero as the video conference scenes do. We obtain similar functions when all of the intrascene frames (excluding the rst two frames of each scene) are treated as a single time series. The left side of Fig. 12.10 shows this function for im and Isaura 1. This method of estimating the autocorrelation function ignores scene boundaries. For example, the last frame of a scene and the rst (counted) frame of the subsequent scene contribute to the lag one term in the autocorrelation function. For lm, this causes the autocorrelation function to have periodic pulses, as shown in Fig. 12.10(c). These pulses are not present in the autocorrelation functions of the rst six scenes and are just an artifact of the aggregation across scenes. A more re ned estimate is obtained by dividing the data into scenes, calculating the empirical autocorrelation function for each scene, and then averaging over the scenes. To be
