This paper describes a new approach to pitch marking. Unlike other approaches that use the same combination of features for the whole signal, we take into account the signal prope...
A feature extraction method using multi-frequency bands is proposed for face recognition, named as the Multi-band Gradient Component Pattern (MGCP). The MGCP captures discriminativ...
