Abstract :
This paper introduces the paradigm of joint time- frequency-shape analysis of discrete-time signals by means of a novel transform called discrete shapelet transform (DST). This approach allows one to And the time-support of frequencies, and, at the same time, analyze a shape. Applications are possible for a diversity of fields in signal processing, and the results assure the efficacy of the proposed transform.
