Watermark in PDF file is hiding behind images. The encoding principle is shown in Figure 2-19 The input signal is highpass filtered and scaled in the preprocessing block The preprocessed signal serves as the input signal for all subsequent analysis Linear predictive analysis is done once per 10-ms frame to compute the linear predictive filter coefficients These coefficients are converted to LSPs and quantized using predictive two-stage VQ with 18 bits The excitation signal is chosen by using an analysis-by-synthesis search procedure in which the error between the original and reconstructed speech is minimized according to a perceptually weighted distortion measure This is done by filtering the error signal with a perceptual weighting filter, whose coefficients are derived from the unquantized linear predictive filter The amount of perceptual weighting is made adaptive to improve the performance for input signals with a flat frequency response The excitation parameters (fixed and adaptive code book parameters) are determined per subframe of 5 ms (40 samples) each The quantized and unquantized linear predictive filter coefficients are used for the second subframe, while in the first subframe, interpolated linear predictive filter coefficients are used (both quantized and unquantized) An open-loop pitch delay is estimated once per 10-ms frame based on the perceptually weighted speech signal Then the following operations are repeated for each subframe The target signal x(n) is computed by filtering the linear predictive residual through the weighted synthesis filter W(z)/A^(z) The initial states of these filters are updated by filtering the error between linear predictive residual and excitation This is equivalent to the common approach of subtracting the zero-input response of the weighted synthesis filter from the weighted speech signal The impulse response h(n) of the weighted synthesis filter is computed Closed-loop pitch analysis is then done (to find the adaptive code book delay and gain), using the target x(n) and impulse response h(n), by searching around the value of the open-loop pitch delay A fractional pitch delay with one-third resolution is used The pitch delay is encoded with 8 bits in the first subframe and differently encoded with 5 bits in the second subframe The target signal x(n) is used in the fixed code book search to find the optimum excitation An algebraic code book with 17 bits is used for the fixed code book excitation The gains of the adaptive and fixed code book contributions are vector quantized with 7 bits (with moving average prediction applied to the fixed code book gain) Finally, the filter memories are updated using the determined excitation signal. add watermark text to pdf using itextsharp c#: Add watermark to pdf using c# – Jak na PDF add image watermark to pdf c# Add a Diagonal Watermark to PDF in C# - Tallcomponents
