Imperative visual data frequently vanishes when color applications are seen by partially color blind users. A new method for adaptive interface for accommodating color blind users is presented. The method presented here has two sections: 1) test client perceivability by utilizing Ishihara plates. 2) change the interface color scheme to accommodate color blind users if necessary. We demonstrate ...

Speckle reduction techniques are applied to SAR imagery to produce images that are almost photographic in appearance ("quasi-photographic imagery"). A road tracking system designed for use with photographic imagery has been used to process this data. The road networks extracted from the quasi-photographic imagery are compared with those produced from optical imagery. It was found that the perfo...

Abs t rac t . In this paper, a new approach for retrieval from semistructured photographic collections is described. We have developed a retrieval model based on the Dempster-Shafer theory of evidence combination. Basic concepts of the Dempster-Shafer theory are explained and the suitability of this theory for information retrieval is explored. A retrieval model for a semi-structured photograph...

As the study of complex systems has become dominant in physics the link between computational and physical science has become ever more important. In particular, with the rising popularity of imaging techniques in physis, the development and application of cutting edge computer vision techniques has become vital. Here we present novel image analysis methods which can be used to extract the posi...

An innovative approach to date fiber-based gelatin silver prints using near-infrared spectroscopy (NIR) and multivariate analysis is presented. NIR spectra were acquired for 152 film stills printed in the USA between 1914 and 1986, and partial least square (PLS) analysis was used to correlate the spectra with the year the photographs were printed. Principal component analysis and spectral inter...

In this study we investigate the effect of detector size in the dosimetry of small fields and steep dose gradients with a particular emphasis on IMRT measurements. Comparisons of calculated and measured cross-profiles and absolute dose values of IMRT treatment plans are presented. As a consequence of the finite size of the detector that was used for the commissioning of the IMRT tool, local dis...

ROBERT BARTLETT HAAS, Muybridge. Man in motion, Berkeley, Los Angeles, and London, University of California Press, 1976, 4to, pp. xi, 207, illus., £12.00. The English-born photographer, Eadweard Muybridge (1830-1904) was the first to capture instantaneous motion on film and to project it on a screen, and the first successfully to develop a method of analysing movement into continuous series of ...

slides over the barrel of the microscope and holds the cell flat against the ocular lens or the end of the lens barrel if the ocular lens is not used. All the light passing through the optical system of the microscope is intercepted by the cell. The camera speed is adjusted to fit the light intensity, or the light intensity is regulated by rheostat or diaphragm to conform with a desired film ve...

This paper discusses a 13.89 million pixels CMOS image sensor for digital SLR cameras. The pitch of the 3transistor active pixel is 8 microns. The sensor has a full well charge of 117K electrons and 33 electrons temporal noise, and a dynamic range of 71 dB. The fixed pattern noise is 0.14% RMS, obtained by an on-chip correction circuit. Color filters have been optimized for best photographic pe...
