Phase-sensitive imaging techniques, suitable for investigating structures in the micron range, are discussed in this book with a focus on optical coherence tomography (OCT). The probed samples are mostly of technical nature, but the methods in general are not restricted to technical applications. Moreover, several imaging aspects, originating from biological applications, recently have been transferred to technical material sciences. OCT imaging is presented here mainly by its phase-sensitive modifications: polarization-sensitive OCT (PS-OCT) and differential phase contrast OCT (DPC-OCT). The comparison to quantitative imaging in phase contrast microscopy techniques has been drawn to illustrate the similarities, differences, and limitations of both techniques. The potential for appropriate image processing is demonstrated in this context to obtain improved quantitative and localized information about specimens and material behavior. The book connects the field of optics, mathematics, and image processing from an interdisciplinary point of view.

Film Speed
29,90 € *
ggf. zzgl. Versand

Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. Relatively insensitive film, with a correspondingly lower speed index requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a slow film. Highly sensitive films are correspondingly termed fast films. A closely related ISO system is used to measure the sensitivity of digital imaging systems. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types).

Image Segmentation and Mesh Generation
49,90 € *
ggf. zzgl. Versand

In this book, we investigate a super-pixel based scheme that integrates both image segmentation and mesh generation into a single method, making mesh generation truly an image-incorporated approach. Our method, called image content-aware mesh generation, consists of several main steps. First, we generate a set of feature-sensitive and adaptively distributed points from 2D grayscale images or 3D volumes. Second, a Delaunay-triangulation generator (2D) or tetrahedral mesh generator (3D) is then utilized to generate a 2D triangulation or 3D tetrahedral mesh. A graph-cut method is then applied to the graph to define the boundary between two subsets of the graph, resulting in good boundary segmentations with high-quality meshes.

Turin Shroud: Testament to a Lost Technology
41,90 € *
ggf. zzgl. Versand

The heated debate still rages as to how the seemingly miraculous, life-size, two-fold image of the crucified Christ appeared on the Shroud of Turin. Was it the actual burial cloth which wrapped Christ's body 2000 years ago or was it simply a clever medieval forgery? Prof Nicholas Allen, the originator of the photographic hypothesis for image formation on the Shroud of Turin, has been researching this phenomenon since 1988. He shares the secrets of how medieval alchemists managed to make this incredible image over 600 years ago and successfully addresses, inter alia, the following issues: The historical evidence for persons knowing about the camera obscura, lenses and light-sensitive chemicals before c. 1357. He also shares with you his exhaustive, practical experimentation in order to ascertain the possibility of producing an image which duplicates the characteristics of the Shroud of Turin employing only those substances and equipment that existed in a medieval society.

ggf. zzgl. Versand

In order to keep the data confident and secure under transmission, there is a need to encode the data as well as to hide the existence of data. In this book, ECCSH-DNA is proposed to send the sensitive data securely. For this a combination of steganography and cryptography has been used. Initially data is encrypted with HECC encryption technique and then data is hidden inside the image using DNA steganography.
