Instantaneous frequency measurement of dissipative soliton resonant light pulses
(Optica Publishing Group, 2023)
Instantaneous Phase Threshold for Reflector Detection in Ultrasonic Images
(Institute of Electrical and Electronics Engineers (IEEE), 2014-07-01)
A method for reflector detection, based on the instantaneous phase of the aperture data for ultrasonic images, is proposed. The instantaneous phase (IP) image is obtained by replacing the amplitude information by the ...
Improving ultrasonic imaging of aluminum plates using phase modulation
(2020-01-01)
Conventional techniques for ultrasonic image beamforming use amplitude information to produce the im-ages. Although amplitude images can be obtained with high quality, they can also present limitations regarding dead zone, ...
2D Instantaneous Frequency-based Method for Motion Estimation using Total Variation
(Institute of Electrical and Electronics Engineers, 2014-12)
We present a first approach to a new method to compute the motion estimation in digital videos using the two-dimensional instantaneous frequency information computed using amplitude-modulation frequency-modulation (AM-FM) ...
Infinitely oscillating wavelets and a efficient implementation algorithm based the FFTWavelets infinitamente oscilantes y un eficiente algoritmo de implementación basado en la FFT

Voice Jitter Estimation Using High-Order Synchrosqueezing Operators
(Institute of Electrical and Electronics Engineers, 2020-12)
Voice jitter is defined as a random perturbation of the glottal cycle duration which can be useful for voice parametrization and that usually depends on finding fiducial points in this signal. In this paper, a novel ...
Discriminating broken rotor bar from oscillating load effects using the instantaneous active and reactive powers
(Institution of Engineering and Technology, 2010-04)
A new strategy for detection and diagnosis of broken bars and load oscillations is proposed. The proposed technique is based on the analysis of the instantaneous active and reactive powers spectra, and allows the correct ...
