Frieden B, Gatenby R
Sci Rep
. 2019 Apr;
9(1):6110.
PMID: 30992457
Multiple prior empirical and theoretical studies have demonstrated wire-like flow of electrons and ions along elements of the cytoskeleton but this has never been linked to a biological function. Here...

Wang Y, Frieden B
Appl Opt
. 2010 Nov;
34(26):5938-44.
PMID: 21060430
We investigate a neural net-based algorithm for enhanced imaging through atmospheric turbulence. The concept is based on a standard model of optical turbulence, according to which a short-exposure point-spread function...

Frieden B, Bajkova A
Appl Opt
. 2010 Nov;
34(20):4086-93.
PMID: 21052233
An information divergence, such as Shannon mutual information, measures the distance between two probability-density functions (or images). A wide class of such measures, called α divergences, with desirable properties such...

Frieden B, Bajkova A
Appl Opt
. 2010 Sep;
33(2):219-26.
PMID: 20862011
BaJkova's generalized maximum entropy method for reconstruction of complex signals is further generalized through the use of Kullback-Leibler cross entropy. This permits apriori information in the form of bias functions...

Appl Opt
. 2010 Aug;
31(8):1138-45.
PMID: 20720731
Integral logarithmic transforms (LT's) are defined for both one- and two-dimensional input functions. These have the desirable properties of linearity and invariance to scale change of the input. One of...

Appl Opt
. 2010 Aug;
31(8):1103-8.
PMID: 20720727
A new approach is given for the problem of reconstruction of phase from modulus data. A set of Wiener-filter functions is formed that multiply, in turn, displaced versions of the...

Appl Opt
. 2010 Jun;
29(16):2424-32.
PMID: 20563184
We derive the expression for the 3-D incoherent optical transfer function when third-order spherical aberration is present. The normalized verision of the transfer function is numerically calculated for various amounts...

. 2010 Jun;
28(6):1235-43.
PMID: 20548646
A longstanding problem of estimation is extraction of the signal image from a given noisy image. Here, prior knowledge in the form of a second, template image is also assumed...
