Stable Gabor Phase Retrieval and Spectral Clustering
Abstract We consider the problem of reconstructing a signal f from its spectrogram, i.e., the magnitudes | V φ f | of its Gabor transform urn:x-wiley:00103640:media:cpa21799:cpa21799-math-0001 Such problems occur in a wide range of applications, from optical imaging of nanoscale structures to audio processing and classification. While it is well‐known …
