Evaluation of denoising algorithms for footsteps sound classification in noisy environments
(2021)
Identifying a person using footsteps sounds is part
of the recent research in developing biometrics, systems designed
to identify an individual in a group using body measurements.
The sound of footsteps has a short ...
Spatial Sound Rendering – A Survey
Simulating propagation of sound and audio rendering can improve the sense of realism and the immersion both in complex acoustic environments and dynamic virtual scenes. In studies of sound auralization, the focus has always ...

This work presents a comparative analysis based in qualitative and quantitative criteria between the frequency domain audio processing algorithms Phase Vocoder and Spectral Modeling Synthesis (SMS). The algorithms were ...
Clustering and data reduction algorithm applied to spectra measured with a multi-static HF sounding system in Peru
(2023 CEDAR Workshop, 2023-06)
The HF radar is a network of HF radio beacons and receivers for ionospheric sounding, and it has been operating in Peru since 2016. The purpose of this instrument is to measure the group delay, Doppler shift, power, and ...
A Comparative Study on Denoising Algorithms for Footsteps Sounds as Biometric in Noisy Environments
(2022-08-03)
Biometrics is the automated identification of a person based on distinctive characteristics, such as fingerprints, face, voice, or the sound of footsteps. This last characteristic has significant challenges considering the ...
