Emergence of the phytoplasma clade from an Acholeplasma-like ancestor gave rise to an intriguing group of cell wall-less prokaryotes through a remarkable and continuing evolutionary process. In a ceaseless progression, phytoplasmas have evolved reduced genomes, lost biochemical pathways for synthesis of nutrients supplied by hosts, and gained capabilities for transkingdom parasitism and pathoge...

Fire regimes are ultimately controlled by wildland fuel dynamics over space and time; spatial distributions of fuel influence the size, spread, and intensity of individual fires, while the temporal distribution of fuel deposition influences fire’s frequency and controls fire size. These “shifting fuel mosaics” are both a cause and a consequence of fire regimes. This paper synthesizes results fr...

In this paper, we describe an image-based rendering technique called Inverse Concentric Mosaics (ICM), which is based on Concentric Mosaics (CM) [11]. While CMs allow scenes to be viewed from inside looking out, ICM permits the user to visualize objects from the outside looking in. ICM has the following advantages: viewpoints of objects can be changed in a continuous manner and at interactive s...

red and color video data acquired by moving cameras under the constraints of small and large motion parallaxes. We distinguish between techniques for image sequences with small motion parallaxes and techniques for image sequences with large motion parallaxes and we describe techniques for building the mosaics for the purpose of under vehicle inspection and visualization of roadside sequences. F...

A novel hardware independent real-time aerial image stabilization and mosaicing system is developed for mini UAV surveillance and remote sensing operations. In order to measure the quality of the constructed mosaics, several in-door and flight tests were performed. A novel mosaic quality measurement method utilizing 5 axis CNC for 3D positioning of the camera and printed high resolution aerial ...

A key component of many Byzantine churches was the mosaics on the curved walls and ceilings, which included gold and silver glass tesserae. As the viewer or the light moved within the church, these tesserae sparkled. In this paper we describe how we captured a Polynomial Texture Map of the apse mosaic at the Angeloktisti Church at Kiti, Cyprus and used it to investigate how the position of the ...

The aim of the MOSAIK-project is to test alternative management systems regarding their efficiency in maintaining the characteristic species composition of dry grasslands. We present an integrated landscape model approach to test an alternative management system for applicability in preserving dry grasslands. By rototilling, i.e. cyclic, massive disturbance in the vegetation cover, we establish...

We describe an image stabilization system that compensates the motion of a moving platform carrying a camera. The dynamic construction of an image mosaic allows the selection of a reference image (normally the first of the sequence) and the registration of every incoming image with the reference frame. A feature-based mosaicking system is proposed in this paper to achieve image stabilization. T...
