Identificación del arma y la munición utilizadas en un disparo con técnicas conexionistas

Resum

In this work, a first approach to the problem of the sound based identification of the arms and ammunitions employed in a shot is presented, working with a data set limited to a few classes of arms and ammunitions. Data recordings were made in four different environments: a sound proof closed room (inside shooting gallery), an specific open space (outside gallery), a non-prepared closed space (room) and a normal open space (field). The two former spaces were the shooting galleries of the Police Scholl in Avila (Spain). These four environments were chosen in an attempt to emulate the actual situations where, eventually, the system could be used.
