There is little information describing the match running demands of elite-level Australian Rules Football (AF). The aims of this study were to examine: (1) match running demands; and (2) the influence of periods of increased physical activity on subsequent running performance in the Australian Football League. Time-motion analyses were performed 1-9 times per player from 16 professional AF play...

In our daily perception of facial expressions, we depend on an ability to generalize across the varied distances at which they may appear. This is important to how we interpret the quality and the intensity of the expression. Previous research has not investigated whether this so called perceptual constancy also applies to the experienced intensity of facial expressions. Using a psychophysical ...

The effect of incidence angle on the intensity of laser backscatter has been studied in photonics and optics, but the applications of these results to remote sensing of natural land targets are limited, as well as the availability of experimental validation data for airborne and terrestrial laser scanning, where the incidence angle correction using the Lambertian scattering law is common. We ha...

This study aims to investigate the characteristics of LIDAR intensity data for executing land cover classification. The quantitative and qualitative analysis was executed with reflection geometry model and land cover classification data. By these analyses, the LIDAR intensity feasibility for classification was discussed. The survey found that intensity is inversely proportional to angle and dis...

the quantitative analysis of cardiac motions in echocardiography images is a noteworthy issue in processing of these images. cardiac motions can be estimated by optical flow (of) computation in different regions of image which is based on the assumption that the intensity of a moving pattern remains constant in consecutive frames. however, in echocardiographic sequences this assumption may be v...

Metal surfaces and nanostructures interact with fluorescent materials, enhancing or quenching the fluorescence intensity, modifying the fluorescent lifetime, and changing the emission frequency and linewidth. These interactions occur via several mechanisms, including radiationless energy transfer, electric field enhancement, and photonic mode density modification. The interactions display a str...
