Otherwise, a decline in the rate of classification accuracy would have been trivial considering that the classification had been applied for exposure realizations separately (an accurate classification in this case requires two separate classification procedure for each of the exposure realizations and both procedures must identify each of the realizations in the true exposure group).
Let us consider that the rate of influenza cases in non-epidemic periods is a random variable X and that a database contains weekly realizations of such variable.
The volume of the intersection part in 3D gamut, the realization rate of target gamut, and the gamut efficiency are calculated for the ITU-R BT.2020/laser and ITU-R BT.709/laser, respectively, and the results are shown in the following.
As in the Chôan dialect, the realization rate of [l] is in general negatively correlated with speaker age, while that of [z]/[dz] is positively correlated.
However, for the new recommendation UHDTV, the intersection volume is 16.96 × 105, the realization rate of laser's target gamut is 95.12% and the value of the gamut efficiency is 94.43%.
Therefore, the realization rate of target gamut and the gamut efficiency [12, 13] are defined for the displayers as formulae (4) and (5) follow: Realization rate of target gamut = V Equipment gamut ∩ V Target gamut V Target gamut × 100%% (4) Gamut efficiency = V Equipment gamut ∩ V Target gamut V Equipment gamut × 100%% (5).
As showed in Table 4, the intersection volume between laser TV and the system of ITU-R BT.709 is 7.86 × 105, the realization rate of laser's target gamut is 100%, but the gamut efficiency is only 43.76%.
In order to get a good display effect, the intersection volume should be close to the target gamut volume so that the realization rate of target gamut is close to 100%.
This article also puts forward the realization rate of target gamut and gamut efficiency as the important parameters to evaluate the 3D reproduction ability of the displayer, thereby the objective evaluation system is created for the displayer.
The three-way competition among [z]/[dz], [l], and before an unrounded high vowel/glide is age-dependent, and is especially intense between the former two, with being a rather minor form, the realization rate of which hovers only around 10% at most for all age groups (Ang 洪惟仁 2003, 2012).
