The smooth spectrum corresponding to MFCC is derived by computing a 128-point inverse discrete cosine transform of 13-dimensional MFCC feature.
Encoding of a K-sparse, discrete-time signal of dimension N is accomplished by computing a measurement vector y that consists of M << N linear projections of the vector x.
Control of a target polymer chain length distribution is achieved by first computing a discrete sequence of reactor temperature setpoints which lead to the best match of a given target weight chain length distribution at a final desired monomer conversion.
The visibility of a surface voxel onto a given camera is assessed by computing the discrete ray originating from its optical center to the center of this voxel using Bresenham's algorithm and testing whether this ray intersects with any other foreground voxel.
Finally, the MFCC sequence is obtained by computing the Discrete Cosine Transform (DCT) of the logarithm of the energy sequence : (10).
The power spectrum density (PSD) was obtained by
The short-time spectra were obtained by computing the discrete Fourier transform of segments, 150 samples each, Hanning window, and 100 samples overlap of each segment.
The short-time spectra were obtained by computing the discrete Fourier transform of segments of 150 samples each, the Hanning window and a 100-sample overlap of each segment.
An MR image is usually reconstructed by computing the inverse discrete Fourier transform of the raw data.
The watershed line is computed on a discrete image, by immersion simulation, locating it on the meeting points of several catchment basins (Figure 10).
