Six preprocessing algorithms for the detection of
firearm gunshots are statistically evaluated, using the receiver
operating characteristic method as a previous feasibility metric
for their implementation on a low-power VLSI circuit. Circuits
are intended to serve as the input detection sensors of a low-power
environmental surveillance network. Some possible VLSI implementations
for the evaluated algorithms are also evaluated.
Results indicate that the use of wavelet bank filters, either discrete
or continuous, might be the best choice in terms of the compromise
between detection efficiency and the power requirements of the
intended application.
