A desktop scanner was colorimetrically characterized to average CIELAB error of less than unity for Kodak Ektachrome transparencies and Ektacolor paper, and Fuji Photo Film Fujichrome transparencies and Fujicolor paper. Independent verification on spectrally similar materials yielded average ∆E*ab error of less than 2.1. The technique first modeled the image formation of each medium using eithe...

Concerns arise that the current standard of double-precision floating-point may no longer be sufficient for today’s large-scale numerical simulations. One approach to solve this problem will be to switch to a wider floating-point format: the upcoming quadrupleprecision standard is introduced and compared to currently available software-based approaches. Another complimentary approach is to use ...

We show how to determine the transmittance of short focal length lenses (f approximately 19 mm and f approximately 2 5 mm, in this case) with a combined uncertainty of 3 parts in 10(4) or better by measuring transmittances of lens pairs of a set of three or more lenses with the same nominal focal length. Uncertainties are minimized by optimizing the radiometric design of the setup and the measu...

Multi-protein complexes are ubiquitous and play essential roles in many biological mechanisms. Single molecule imaging techniques such as electron microscopy (EM) and atomic force microscopy (AFM) are powerful methods for characterizing the structural properties of multi-protein and multi-protein-DNA complexes. However, a significant limitation to these techniques is the ability to distinguish ...

For the past 50 years, atomic standards based on the frequency of the cesium ground-state hyperfine transition have been the most accurate time pieces in the world. We now report a comparison between the cesium fountain standard NIST-F1, which has been evaluated with an inaccuracy of about 4 x 10(-16), and an optical frequency standard based on an ultraviolet transition in a single, laser-coole...

Head pose estimation is recently a more and more popular area of research. For the last three decades new approaches have constantly been developed, and steadily better accuracy was achieved. Unsurprisingly, a very broad range of methods was explored statistical, geometrical and tracking-based to name a few. This paper presents a brief summary of the evolution of head pose estimation and a glim...

The research presented in this paper aims to bridge the gap between the latest scientific advances in autonomous vehicle localization and the industrial state of the art in autonomous warehousing. Notwithstanding great scientific progress in the past decades, industrial autonomous warehousing systems still rely on external infrastructure for obtaining their precise location. This approach incre...

In this paper, a novel weighted graph based decision tree optimization algorithm is proposed. The graph is a compact representation of most possible solutions for the decision tree based classifications. The optimal decision tree is then be extracted from it using the N-level prediction technique. The prediction technique can incorporate future knowledge about classifications based on the tree ...

The paper presents experiments and results related to morpho-syntactic (MS) tagging of a highly inflectional language, based on combining language models (LM) learnt from multiple register-diversified corpora. To cope with a large tagset (614 tags), our underlying tagger uses a hidden smaller tagset (92 tags), mapped back, after the proper tagging, into the initial tagset. The same text is tagg...

One of the critical tasks in Computer Vision is Detection and Tracking of objects. But still now, the issues related to this are developing. For the automatic detection of moving objects, some of the monitoring systems cannot able to find the difference, when the difference of brightness between the background and the moving objects is small. The costs are very high in these systems. Most of th...
