Phase Retrieval from STFT Measurements via Non-convex Optimization

open access: yes, 2017
The problem of recovering a signal from its phaseless short-time Fourier transform (STFT) measurements arises in several applications, such as ultra-short pulse measurements and ptychography.

Depthwise spatio-temporal STFT convolutional neural networks for human action recognition

open access: yes, 2020
Conventional 3D convolutional neural networks (CNNs) are computationally expensive, memory intensive, prone to overfitting, and most importantly, there is a need to improve their feature learning capabilities.

Non-Convex Phase Retrieval From STFT Measurements

open access: yes, 2017
The problem of recovering a one-dimensional signal from its Fourier transform magnitude, called Fourier phase retrieval, is ill-posed in most cases. We consider the closely-related problem of recovering a signal from its phaseless short-time Fourier ...

Comparison of STFT and Wavelet Transform inTime-frequency Analysis

open access: yes, 2015
The wavelet transform technique has been frequently used in time-frequency analysis as a relatively new concept. Compared to the traditional technique Short-time Fourier Transform (STFT), which is theoretically based on the Fourier transform, the wavelet

STFT Phase Retrieval: Uniqueness Guarantees and Recovery Algorithms [PDF]

open access: yes, 2016
The problem of recovering a signal from its Fourier magnitude is of paramount importance in various fields of engineering and applied physics. Due to the absence of Fourier phase information, some form of additional information is required in order to be
