A shift in the wavelength of maximum fluorescence emission toward higher wavelengths, caused by a shift in the excitation wavelength toward the red edge of the absorption band, is termed the Red Edge Excitation Shift (REES). This effect is mostly observed with polar fluorophores in motionally restricted media such as very viscous solutions or condensed phases. In this paper, we report the red e...

Leaf and canopy nitrogen (N) status relates strongly to leaf and canopy chlorophyll (Chl) content. Remote sensing is a tool that has the potential to assess N content at leaf, plant, field, regional and global scales. In this study, remote sensing techniques were applied to estimate N and Chl contents of irrigated maize (Zea mays L.) fertilized at five N rates. Leaf N and Chl contents were dete...

A 1-plane graph is a graph embedded in the plane such that each edge is crossed at most once. A NIC-plane graph is a 1-plane graph such that any two pairs of crossing edges share at most one endvertex. An edge partition of a 1-plane graph G is a coloring of the edges of G with two colors, red and blue, such that both the graph induced by the red edges and the graph induced by the blue edges are...

This survey is devoted to problems and results concerning covering the vertices of edge colored graphs or hypergraphs with monochromatic paths, cycles and other objects. It is an expanded version of the talk with the same title at the Seventh Cracow Conference on Graph Theory, held in Rytro in September 14-19, 2014. 1 Covers by paths and cycles In this survey r-coloring always means edge-colori...

In this paper we investigate certain random processes on graphs first suggested by Persi Diaconis. These processes are related to the so-called Tsetlin library random walk as well as to some variants of the classical voter model. A specific example of what we study is the following. Suppose we begin with some finite graph G in which each vertex of G is initially arbitrarily colored red or blue....

The red eye artifacts are troublesome problem of consumer photos. Correction of red eyes without user intervention is an important task. The novel method of automatic detection of red eyes is proposed. This approach is based on application of color information via 3D tables and edge information via directional edge detection filters. For classification a cascade of classifiers including AdaBoos...

Active ground optical remote sensing (AGORS) devices mounted on overhead irrigation booms could help to improve seedling quality by autonomously monitoring seedling stress. In contrast to traditionally used passive optical sensors, AGORS devices operate independently of ambient light conditions and do not require spectral reference readings. Besides measuring red (590-670 nm) and near-infrared ...

Artistic diversiform leaf color is an important agronomic trait that affects the market value of ornamental kale. In the present study, genetic analysis showed that a single-dominant gene, Re (red leaf), determines the red leaf trait in ornamental kale. An F2 population consisting of 500 individuals from the cross of a red leaf double-haploid line 'D05' with a white leaf double-haploid line 'D1...

Direct application of conventional models for sub-voxel edge detection to modalities with intricate image formation like MRI results in systematic edge dislocations on a sub-voxel scale (edge aberration). By quantitative experimental analysis of this effect, a simple correction term can be calibrated, which is demonstrated to improve edge localization precision by a factor of 2.5 to surpass vox...
