Recent developments in intelligence surveillance camera systems have enabled more research on the detection, tracking, and recognition of humans. Such systems typically use visible light cameras and images, in which shadows make it difficult to detect and recognize the exact human area. Near-infrared (NIR) light cameras and thermal cameras are used to mitigate this problem. However, such instru...

Orussus melanosoma Lee & Wei, sp. nov. from South Korea is described and illustrated. Phylogenetic analyses place the new species basally in Orussus, together with other species from the Far East. A key to species of Orussidae from the eastern Palaearctic is provided. 

The genus Margaiostus Stibick, 1978, previously known from North and South America, is recorded for the first time in the fauna of the Palaearctic region. M. sundukovi sp. nov. is described from the Far East of Russia. The position of this species within the genus and the distribution of Margaiostus are discussed.

Depth computation is an attractive feature in computer vision. The use of traditional perspective cameras for panoramic perception requires several images, most likely implying the use of several cameras or of a sensor with mobile elements. Moreover, misalignments can appear for non-static scenes. Omnidirectional cameras offer a much wider field of view (FOV) than perspective cameras, capture a...

The use of consumer digital cameras or webcams to characterize and monitor different features has become prevalent in various domains, especially in environmental applications. Despite some promising results, such digital camera systems generally suffer from signal aberrations due to the on-board image processing systems and thus offer limited quantitative data acquisition capability. The objec...

In this study, the effect of light wavelength on growth rate and lipid production of Synechocystis was investigated. Continuous cultivation system was used to have uniform cell density and avoid self-shading in order to obtain more precise results. Based on previous studies, red light is more efficient than other colors in the visible spectrum for cultivation of Synechocystis; however, the opti...

The spectral response function of a camera maps the relative sensitivity of the camera imaging system as a function of the wavelength of the light. The spectral response function of the colour channels of a commercial-off-theshelf (COTS) Red/Green/Blue (RGB) camera is often unknown and not typically provided by the manufacturer of the camera. Knowledge of this response can be useful for a wide ...

Light-field imaging systems have received a lot of attention recently, especially with the release of Lytro cameras for consumer application. Conventional cameras capture 2D images, which are projections of a 3D scene. Light-field imaging systems capture not only the projection but also the directions of incoming lighting that project onto a sensor. Specifically, Lytro camara consist of an arra...

background and objectives : due to the extensive use of antibiotics, the spread of drug-resistant bacteria is one of the most worrisome threats to public health. one strategy that can be used to overcome potential shortcomings might be the inactivation of these organisms by photodynamic therapy. in this study, we have investigated whether drug-resistant wound-associated organisms (staphylococcu...

Specific binding of 3H-ouabain and ruthenium red (RR) to membranes of T-tubules in crayfish muscles was used to identify the subfraction containing vesicles originating from the T-system. The microsomal fraction was prepared by differential centrifugation, and subfractions were separated in continuous or discontinuous sucrose density gradients. 3H-ouabain binding was estimated by scintillation ...
