Speech classification is an important research topic in the speech signal processing area. Rapidly and concisely speed classification is meaningful for speech coding and speech synthesis. For the deficiency of currently available classification features and classification algorithms, this paper proposes a novel algorithm through using the energy distribution within each frequency band in Mel-frequency...
Extracting invariable features is one key issue for 3D model searching. A novel invariable feature extraction method, namely geometry projection based histogram model, is proposed for 3D model description. Different from the traditional method, one projection plane (or surface) is created for each 3D model, and the points of 3D models are projected to the projection plane (or surface), and then the...
