TLDR
In this paper, the acquisition and use of digital images in a wide variety of scientific fields is discussed. But the focus is on high dynamic range imaging in more than two dimensions.Abstract:
"This guide clearly explains the acquisition and use of digital images in a wide variety of scientific fields. This sixth edition features new sections on selecting a camera with resolution appropriate for use on light microscopes, on the ability of current cameras to capture raw images with high dynamic range, and on imaging in more than two dimensions. It discusses Dmax for X-ray images and combining images with different exposure settings to further extend the dynamic range. This edition also includes a new chapter on shape measurements, a review of new developments in image file searching, and a wide range of new examples and diagrams"read more

Time-domain reconstruction algorithms and numerical simulations for thermoacoustic tomography in various geometries
TL;DR: This paper presents time-domain reconstruction algorithms for the thermoacoustic imaging of biological tissues to planar and cylindrical measurement configurations and generalizes the rigorous reconstruction formulas by employing Green's function technique.

Nonstationary vortexlike reentrant activity as a mechanism of polymorphic ventricular tachycardia in the isolated rabbit heart.
Richard A. Gray,José Jalife,A.V. Panfilov,William T. Baxter,Candido Cabo,Jorge M. Davidenko,Arkady M. Pertsov +6 more
TL;DR: Polymorphic ventricular tachycardia in the healthy, isolated rabbit heart is the result of either a single or paired ("figure-of-eight") nonstationary scroll waves.

Nonlinear neurons in the low-noise limit: a factorial code maximizes information transfer
Jean-Pierre Nadal,Néstor Parga +1 more
TL;DR: In this article, the authors investigated the consequences of maximizing information transfer in a simple neural network (one input layer, one output layer), focusing on the case of nonlinear transfer functions, and they showed that maximization of information leads to a factorial code-hence to the same solution as required by the redundancy reduction principle of Barlow.

Information Entropy Measure for Evaluation of Image Quality
TL;DR: Experimental results show that the amount of TI is closely related to both image noise and image blurring, which demonstrates the usefulness of the proposed method for evaluation of physical image quality in medical imaging.

Pulsed terahertz tomography
Shaohong Wang,Xi-Cheng Zhang +1 more
TL;DR: In this paper, the phase and amplitude of a terahertz time-domain spectroscopy (THz-TDS) pulse at each frequency can be determined by using a digital holography method.
