In this paper I present a method to enhance the search sensitivity for long
transient Gravitational Waves produced by Neutron Star instabilities. This
method consists in a selective image filter, called Triangular Filter, to be
applied to data spectrograms. It is shown that thanks to this implementation a
20% gain in sensitivity is achievable.
