15 صفحه اولSilver Colloid Particles Preparation by Using Photographic Development System
The colloid silver sols with defined average particle size were prepared by means of chemical reduction of silver compound [Ag(SO3)2] 3– by several organic redox systems used as development agents in photography. The average size of the particles varied from 700 to 150 nm in dependence on sulphite concentration in reaction system and reduction compound type.
متن کاملA computer-assisted system for photographic mark–recapture analysis
1. Photographic mark–recapture is a cost-effective, non-invasive way to study populations. However, to efficiently apply photographic mark–recapture to large populations, computer software is needed for imagemanipulation and patternmatching. 2. We created an open-source application for the storage, pattern extraction and pattern matching of digital images for the purposes of mark–recapture anal...
متن کاملMultiwindowed defocused electronic speckle photographic system for tilt measurement.
Defocused speckle photography has long been used to measure rotations of rough surfaces. By addition of a suitably perforated mask, some measurement properties, such as range and lateral resolution, may be changed at will. In particular, the maximum measurable tilt can be significantly increased, although at the expense of poorer lateral resolution. Advantages of this compared with previously d...
متن کاملSpatially Adaptive Photographic Flash
Using photographic flash for candid shots often results in an unevenly lit scene, in which objects in the back appear dark. We describe a spatially adaptive photographic flash system, in which the intensity of illumination varies depending on the depth and reflectivity of features in the scene. We adapt to changes in depth using a single-shot method, and to changes in reflectivity using a multi...
