Investigating the role of visual information in animal communication often involves the experimental presentation of live stimuli, mirrors, dummies, still images, video recordings or computer animations. In recent years computer animations have received increased attention, as this technology allows the presentation of moving stimuli that exhibit a fully standardized behaviour. However, whether...

n archaeology, measurement and documentation are both important, not only to record endangered archaeological sites, but also to record the excavation process itself. Annotation and precise documentation are important because evidence is actually destroyed during archaeological work. On most sites, archaeologists spend a large amount of time drawing plans, making notes, and taking photographs. ...

This contribution demonstrates an example of experimental automatic image analysis to detect spores prepared on microscope slides derived from trapping. The application is to monitor aerial spore counts of the entomopathogenic fungus Pandora neoaphidis which may serve as a biological control agent for aphids. Automatic detection of such spores can therefore play a role in plant protection. The ...

The digital radiographic process involves (a) the attenuation of x rays along rays forming an orthographic projection, (b) the detection of the radiation beam by a two-dimensional recording device, (c) the processing of detector signals to produce a digital image for presentation, and (d) the display of the digital image. The performance of the process is typically considered in terms of the ab...

This poster documents work recently undertaken at Emory University’s Manuscript, Archives, and Rare Book Library (MARBL) to review policy on disk image file formats used to capture and store digital content in our Fedora repository. Survey of the field and current best practices revealed waning support for the formats previously used and prompted collaborative efforts between Digital Archives s...

BACKGROUND Since the invention of the simultaneous ICG and fluorescein (SIF) videoangiography in 1995 none of the available SLOs were significantly improved. Digital video recording with a PC can simplify and improve the quality of the angiography. METHOD SIF angiography images of a two-wavelength scanning laser ophthalmoscope were digitized with a personal computer and written to disk with a...

In this paper, the distortion of the reconstructed images of the propagating light pulse in transmission light-in-flight holography recording was analyzed. Based on the analysis model, for recording the wavefront more accurately, the optimized selection of relevant parameters was made. Furthermore, a cylindrical lens was introduced to correct the image distortion. Additionally, the light-in-fli...
