Image reconstruction from localized Fourier magnitude
Fourier transform magnitude is, in many cases, the only measurable data in fields such as optics, x-ray imaging, crystallography and astronomy. Spectral phase information is impra...

Improvement of phase-based algorithms for disparity estimation by means of magnitude information
Estimating depth information from two-dimensional stereoscopic image pairs is an important task in image processing. The disparity, i.e. the displacement of corresponding pixels i...

Iterative reconstruction of speech from short-time Fourier transform phase and magnitude spectra
In this paper, we consider the topic of iterative, one dimensional, signal reconstruction (speci´Čücally speech signals) from the magnitude spectrum and the phase spectrum. While ...

A New Alternating Minimization Algorithm for Total Variation Image Reconstruction
We propose, analyze and test an alternating minimization algorithm for recovering images from blurry and noisy observations with total variation (TV) regularization. This algorith...
