Octonion Phase Retrieval

IEEE Signal Processing Letters
Signal processing over hypercomplex numbers arises in many optical imaging applications. In particular, spectral image or color stereo data are often processed using octonion algebra. Recently, the eight-band multispectral image phase recovery has gained salience, wherein it is desired to recover the eight bands from the phaseless measurements. In this

Compressive Phase Retrieval

Digital Holography & 3-D Imaging Meeting, 2015
Sparsity priors improve the condition of ill-posed or undersampled inverse problems. I will discuss how this principle applies to phase retrieval and discuss examples from digital holography, transport of intensity, phase-space tomography, and ptychography. Article not available.
