Adaptive Thinning Algorithm
conference paper
A new adaptive method is presented to display large amounts of data on, for example, a computer
screen. The algorithm reduces a set of N samples to a single value, using the statistics of the
background and cormparing the true peak value in the set of N samples to the expected peak value
of this background, taking into account a possible global trend in the data. The new algorithm
clearly performs better than conventional ones in terms of signal-to-noise ratio.
The algorithm has been successfully applied to display low-frequency active sonar data, used for
Anti-submarine Warfare experiments, where the background followed a Rayleigh distribution.
The algorithm is easy to apply, and can be used for data reduction in one or more dimensions and
for arbitrary background distributions.
