The current standard methods for determination of seagrass status and trends involve mapping from 1:24,000 scale true color, not color infrared, aerial photography (NOAA-CSC 2001). Analysis of this scale color photography for seagrass distribution has traditionally been performed by photointerpretation of 9” x 9” positive phototransparencies, followed by digitization of seagrass polygons from m...

measurement of the joint angles is used to assess the joint position sense (jps). the aim of this study was to introduce a simple, fast, less expensive and objective method of measurement for jps. in the current research, the accuracy and reliability of a system, consist of digital photography, nonreflective markers and manual analysis were evaluated. for this purpose, digital photos were taken...

Stereoscopic photography has a long history which started just few years after the first known photo was taken: 1849 Sir David Brewster introduced binocular camera. Whereas mobile is omnipresent because of wide distribution smart phones, stereoscopic only used by very small set enthusiasts or professional (stereo) photographers. One important aspect that required technology usually quite expens...

This paper introduces the automated characterization of real estate (real property) for Internet mapping. It proposes a processing framework to achieve this task from vertical aerial photography and associated property information. A demonstration of the feasibility of an automated solution builds on test data from the Austrian City of Graz. Information is extracted from vertical aerial photogr...

Composition Context Photography Daniel André Vaquero In the digital point-and-shoot photography paradigm, users typically point the camera at the subjects, adjust framing, and trigger functions such as autofocus in preparation for taking a picture. This dissertation explores the opportunities for expanding the outcome of the point-and-shoot photography process by utilizing additional informatio...

The use of digital images is increasing all the time in personal digital photography, medical imaging, and fingerprint image databases. The goal of this research is to improve the image quality of a given compressed digital image while maintaining the same file size of the image. Wavelet based image compression is improved upon by using Genetic Algorithms on a supercomputer to evolve transforms...

Species designations are critically important scientific hypotheses that serve as the foundational units in a wide range of biological subdisciplines. A growing realization that some classes of data fail to delimit species under certain conditions has led to increasingly more integrative taxonomies, whereby species discovery and hypothesis testing are based on multiple kinds of data (e.g., morp...

This article demonstrates the need always to consider change against continuity and continuity against change in the analysis of mnemonic technologies. It does so by exploring what has happened in the move from analogue to digital photography, looking, in particular, at how this has affected the meanings of personal photographs and the practices of remembering associated with them. In contrast ...
