A Least Squares Approach for Stable Phase Retrieval from Short-Time Fourier Transform Magnitude
Tamir Bendory, Yonina C. Eldar
We address the problem of recovering a signal (up to global phase) from its short-time Fourier transform (STFT) magnitude measurements. This problem arises in several applications,…
Recovery of Sparse Positive Signals on the Sphere from Low Resolution Measurements
Tamir Bendory, Yonina C. Eldar
This letter considers the problem of recovering a positive stream of Diracs on a sphere from its projection onto the space of low-degree spherical harmonics, namely, from its low-r…
Stable Support Recovery of Stream of Pulses with Application to Ultrasound Imaging
Tamir Bendory, Avinoam Bar-Zion, Dan Adam +2
This paper considers the problem of estimating the delays of a weighted superposition of pulses, called stream of pulses, in a noisy environment. We show that the delays can be est…
Convex Optimization Approach for Stable Decomposition of Stream of Pulses
Tamir Bendory
This paper deals with the problem of estimating the delays and amplitudes of a weighted superposition of pulses, called stream of pulses. This problem is motivated by a variety of…
Robust Recovery of Positive Stream of Pulses
Tamir Bendory
The problem of estimating the delays and amplitudes of a positive stream of pulses appears in many applications, such as single-molecule microscopy. This paper suggests estimating…
Super-resolution on the Sphere using Convex Optimization
Tamir Bendory, Shai Dekel, Arie Feuer
This paper considers the problem of recovering an ensemble of Diracs on a sphere from its low resolution measurements. The Diracs can be located at any location on the sphere, not…
