A novel cuboid method with particle swarm optimization for real-life noise attenuation from heart sound signals
The quasi-cyclic feature of heart sound is explored. A novel cuboid method optimized by PSO for attenuating real-life noise from heart sound is proposed. A new objective function for PSO optimizing HS signal de-noising is proposed.
