Standard post-processing of raw video data involves all activities that are necessary to enable a quantitative interpretation of the video data. The Argus system provides a standard environment to do so, named the Argus Runtime Environment. The key component of this environment is the Argus database of meta-information on the video data. This database is being filled by Deltares (to ensure a unique embedding in the worldwide Argus network) and contains all information that is necessary for quantitive image interpretation (i.e. site & station characteristics, type of image processor, cameras and lenses, geometry solutions, meta-information on tides and waves, etc).
The Argus Runtime Environment features the following tools for standard image post-processing:
With the help of standard post-processing techniques, Argus video data can easily be used for the phenomenological analysis of coastal systems and impact assessment studies for nourishments, sand bypassing schemes, etc. Except for the initial set-up of the Argus database (necessarily performed by Deltares), standard post-processing activities can be performed by either Deltares, or the client.
Dedicated image analysis is the advanced analysis of video data to meet the specific goals of a video monitoring project. The ARE offers a suite of operational analysis tools that are available for use by third parties, such as:
Present-day research aims at the development of sophisticated tools for the estimation of subtidal bed elevation, alongshore flow velocities, swash run-up and other nearshore phenomena. Generally, these tools have shown good performance on a single site, but have not been ground-truthed yet over a variety of sites. Research versions of these tools can be provided to clients upon request.
