Abstract :
This paper presents a new algorithm for the cyclification of 1D signals, based on a time×frequency warping. The main goal is to preserve the basic characteristics of the signal, such as low and high frequency regions. The application outlined in this work is the cyclification of motion captured joint curves (near-periodic signals). Also, a method for cyclification of articulated figure motion is presented
