The most frequently used filtering technique to suppress high-frequency noise in GRACE data is the isotropic Gaussian averaging filter. The implementation of the isotropic Gaussian filter in the spherical harmonic domain requires the calculation of filter coefficients, which is performed using either a ...

First, the Gaussian kernel is linearly separable. This means we can break any 2-d filter into two 1-d filters. Because of this, the computational complexity is reduced from O(n2) to O(n). Let’s see an example Applying multiple successive Gaussian kernels is equivalent to applying a sing...
Both implementations are normalizing so that the sum of the coefficients is 1.0. The second implementation computes the sum manually to get an exact figure and is probably the best way to go. The other implementation gives an exact sum for acontinuousversion of the filter. However, discretizing...
Gaussian FIR pulse-shaping filter design collapse all in pageSyntax h = gaussdesign(bt,span,sps)Description h = gaussdesign(bt,span,sps) designs a lowpass FIR Gaussian pulse-shaping filter and returns a vector h of filter coefficients. The filter is truncated to span symbols, and each symbol...

Another aspect of performance is whether a particular blur filter can fit on the GPU. The incremental Gaussian blur algorithm may appear to be small, but the GPU driver will increase the number of instructions dramatically, under certain circumstances. In particular, some GPUs do not have ...
where A is the amplitude; n is the filter order; 𝑤𝑐wc is the central frequency; 𝜃θ is the phase shift; and B represents the filter bandwidth. The suggested GTCC coefficients are computed similarly as in the MFCC coefficient extraction process, where Gammatone filters have been used ...
