Tomographic Reconstruction from Noisy Data
A generalized maximum entropy based approach to noisy inverse problems such as the Abel problem, tomography, or deconvolution is discussed and reviewed. Unlike the more traditional regularization approach, in the method discussed here, each unknown parameter (signal and noise) is redefined as a proper probability distribution within a certain pre-specified support. Then, the joint entropies of ...
متن کاملStructural Variability from Noisy Tomographic Projections
In cryo-electron microscopy, the 3D electric potentials of an ensemble of molecules are projected along arbitrary viewing directions to yield noisy 2D images. The volume maps representing these potentials typically exhibit a great deal of structural variability, which is described by their 3D covariance matrix. Typically, this covariance matrix is approximately low-rank and can be used to clust...
متن کاملTomographic Image Reconstruction in Noisy and Limited Data Settings
Reconstruction of images from projections lays the foundations for computed tomography (CT). Tomographic image reconstruction, due to its numerous real world applications, from medical scanners in radiology and nuclear medicine to industrial scanning and seismic equipment, is an extensively studied problem. The study of reconstructing function from its projections/line integrals, is around a ce...
متن کاملTomographic approach to resolving the distribution of LISA Galactic binaries
The space based gravitational wave detector LISA is expected to observe a large population of Galactic white dwarf binaries whose collective signal is likely to dominate instrumental noise at observational frequencies in the range 10−4 to 10−3 Hz. The motion of LISA modulates the signal of each binary in both frequency and amplitude, the exact modulation depending on the source direction and fr...
متن کاملDetectability of Anomalies from a Few Noisy Tomographic Projections
The problem of detecting an anomaly from a limited number of noisy tomographic projections is addressed from the statistical point of view. An unknown two (or three)-dimensional scene is composed of a background, considered as a nuisance parameter, with a possibly hidden anomaly. A parametric approach is proposed to reduce the lack of a priori information and an optimal test is designed. To dec...
