We present a new algorithm for image restoration in limited-angle chromotomography. The
algorithm is a generalization of the technique considered previously by the authors, based …

The method of projections onto convex sets can be used to solve many problems in image
restoration, eg, restoration from phase, spectral extrapolation, and signal recovery in …

Recently, a new approach to hyperspectral imaging, relying on the theory of computed
tomography, was proposed by researchers at the Air Force Research Laboratory. The …

In an attempt to improve the convergence rates of band-limited image restoration, we derive
and apply two algorithms employing nonlinear projections onto closed convex sets. The …

Image reconstruction from incomplete projection data is strongly required in widespread
applications of computed tomography. This problem can be formulated as a sinogram …

In many applications of computed tomography, it may not be possible to acquire projection
data at all angles, as required by the most commonly used algorithm of convolution …

Image restoration from degraded observations and from properties that the image is
supposed to satisfy has been approached by the method of projections onto convex …

In this paper, the restoration of a degraded image with an auxiliary image from another
sensor is considered. In a typical multispectral satellite imaging system, multiple images …

In this paper we propose an approach of image restoration from multispectral data provided
by an imaging system. We specifically address two topics:(i) Development of a multi …

Images obtained with optical microscopes are often blurred and corrupted by noise.
Specially in wide-field microscopy, there is a strong out-of-focus blur in focal plane direction …
