Phase processing or equivalently group delay processing of speech signals are known to be difficult due to large spikes in the phase/group delay functions that mask the formant structure. In this study, we first analyze in detail the z-transform zero patterns of short-term speech signals in ...
These algorithmic improvements are relevant to the adjacent single look complex (SLC) image slices merging to the multitemporal residual orbital artifacts mitigation and to the phase unwrapping procedure enhancement. Subsequently, the effectiveness of the extended P-SBAS processing chain is shown through ...
The west embankment, which is approximately 11 km long, represents the initial phase of construction; it dates back to the early 1980s and connected the narrowest locations of the western and eastern parts of the lake. The east embankment, with an approximate length of 3 km, was ...

A spatial algorithm to reduce phase wraps from two dimensional signals in fringe projection profilometry 2016, Optics and Lasers in Engineering Citation Excerpt : In the case of the frequency shift method, shifts can only be measured in terms of an integer number of pixels. This causes a residua...
Joshimath has received much attention for its massive ground subsidence at the beginning of the year. Rapid urbanization and its unique geographical location may have been one of the factors contributing to the occurrence of this geological disaster. In
Based on the phase unwrapping algorithm, the three-way asymmetrical output of the 3×3 coupler and demodulation state characteristics of the system when the vibration signal includes high harmonic waves are analyzed in simulations. The result shows that when the three-way output is asymmetrical, ...
1(a) shows one of four phase-shifted fringe patterns. Phase extracted using phase-shifting algorithm is shown in Fig. 1(b), which is obviously very noisy. On the contrary, carrier technique with Fourier transform processes the whole frame of a fringe pattern at the same time. It is more...
