Nearshore sandbars, an important natural defense
mechanism of the beaches, can be monitored using shore-based
video systems. Before studying bar dynamics with video images,
we must establish the relationship between the real bar positions
and the videoed bar positions (detected by the preferential wave
breaking on the shallows)
