A stereoscopic approach for three dimensional tracking of marine biofouling microorganisms
نویسندگان
چکیده
The extraction and analysis of three dimensional tracking data relating to surface exploration of sessile marine organisms is of great importance for understanding the mechanism of surface colonization (biofouling). The knowledge of behavior can thus be used to develop tools for controlling and influencing undesirable impacts that arise as a consequence of the adhered organisms. This paper describes a stereoscopic system currently in development for tracking barnacle cyprids and allows extraction of 3D swimming patterns for a common marine biofouling organism Semibalanus balanoides. The details of the hardware setup and the calibration object are presented and discussed. In addition we describe the algorithm for the camera calibration, object matching and stereo triangulation. As practical result, several trajectories of living cyprids are presented and analyzed with respect to statistical swimming parameters.

Three Dimensional Tracking of Exploratory Behavior of Barnacle Cyprids Using Stereoscopy
Surface exploration is a key step in the colonization of surfaces by sessile marine biofoulers. As many biofouling organisms can delay settlement until a suitable surface is encountered, colonization can comprise surface exploration and intermittent swimming. As such, the process is best followed in three dimensions. Here we present a low-cost transportable stereoscopic system consisting of two...
متن کاملScreening of biofouling activity in marine bacterial isolate from ship hull
Biofouling is the undesirable accumulation of microorganisms, plants, algae and animals on submerged structures especially ship hulls. Biofouling also occurs on the surface of living marine organisms. It is also found on membrane systems such as membrane bioreactors and reverse osmosis spiral wound membranes. In the same manner, it is found in cooling water cycles of large industrial equipments...
