These models, formally known as linear parameter varying (LPV) models, tend to be difficult to identify because they contain a large amount of coefficients that require calibration.
When compared with DCT, DWT, and alternate transforms, the NCST has superior capacity and offers a large amount of coefficients for the watermarking process.

Figure 13 All bands encrypted with an increasing amount of manipulated coefficients and maximum shift values.
Figure 12 All bands encrypted with an increasing amount of manipulated coefficients and a maximum shift value of 128.
In Figures12 and13, it can be seen that varying the amount of manipulated coefficients is a sound approach to vary the strength of visual security.
Then two test runs were performed where all three frequency bands are manipulated with a static maximum shift value but an increasing amount of manipulated coefficients.
Table 4 shows that the proposed T2 chart performs significantly better than MEWMA and MCUSUM charts in different amount of correlation coefficients.
Therefore, the authors conjectured that this happens as a result of fall in the amount of DCT coefficients information which is available for B frames due to processes of rate control and motion compensation.
The figure also shows that only small amount of wavelet coefficients are non-zero, i.e., the radar signal is sparse and can be observed by CS. Figure 5 shows that the evaluation index can reflect the change trend of reconstruction error well with no prior knowledge about radar signal.
We therefore run two MXL: one with all coefficients normally distributed except the constant and the amount of remuneration coefficient (MN1) and the other with only the constant term fixed (MN2).
Plus, the amount of correlation coefficient (R 2) was calculated from the slope and intercept of the drawing of q t versus t 1.2.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
