Improving agnostic searches of Gravitational Waves from Neutron Star instabilities using image filtering

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.
