Mirrors have been used to enable wide field-of-view (FOV) catadioptric imaging. The mapping between the incoming and reflected light rays depends non-linearly on the mirror shape and has been well-studied using caustics. We analyze this mapping using the two-plane lightfield parameterization, which provides valuable insight into the geometric structure of reflected rays. Using this analysis, we...

Pathogenicity and genetic diversity of Fusarium oxysporum from geographically widespread native Gossypium populations, including a cotton growing area believed to be the center of origin of VCG 01111 and VCG 01112 of F. oxysporum f. sp. vasinfectum (Fov) in Australia, was determined using glasshouse bioassays and AFLPs. Five lineages (A-E) were identified among 856 isolates. Of these, 12% were ...

In interventional neuroradiology, three-dimensional rotational digital subtraction angiography (3D-DSA) is very useful for the spatial grasp of the location and size of an intracranial cerebral aneurysm. The purposes of this study were to evaluate the property of three-dimensional image dependence on the respective field of view (FOV) size in a flat-panel detector (FPD) using vessel phantoms, a...

Previous preparation was not required for the study that was performed with an abdominal surface coil, in a Magnetom Avanto 1.5 T equipment (Siemens Medical System; Erlangen, Germany) with, respectively, T2-weighted sequences in the sagittal plane (FOV: 180 mm; thickness: 3.0 mm; GAP: 10%; matrix: 320 × 70; NEX: 3; TA: 2:34 min; TR: 2970; TE: 114), axial plane (FOV: 180 mm; thickness: 3.0 mm; G...

OBJECTIVE To analyze morphological macular changes after uncomplicated cataract surgery and their correlation with age and arterial hypertension. METHODS Total macular volume (TMV), foveal volume (FOVOL) and foveal thickness (FOV) in patients who had undergone cataract surgery were measured using OCT3 Stratus before surgery, the day after the intervention and one month later. The data were an...

Non-overlapping field-of-view (FOV) cameras are used in surveillance system to cover a wider area. Tracking in such systems is generally performed in two distinct steps. In the first step, people are identified and tracked in the FOV of a single camera. In the second step, re-identification of the people is carried out to track them in the whole area under surveillance. Various conventional fea...

The plant defensin NaD1, from Nicotiana alata, has potent antifungal activity against a range of filamentous fungi including the two important cotton pathogens, Fusarium oxysporum f. sp. vasinfectum (Fov) and Verticillium dahliae. Transgenic cotton plants expressing NaD1 were produced and plants from three events were selected for further characterization. Homozygous plants were assessed in gre...

Most of the existing panoramic cameras have cylindrical field of view (FOV) which has a 360 width in azimuth, but a limited height in elevation. However, a hemispherical (or near spherical) FOV is highly desirable in many applications such as robot navigation and surveillance. This paper presents a planarmirror-based panoramic camera (HEM) which is capable of acquiring nearly hemispherical FOV ...
