The goal of this paper is to introduce a complete analysis/resynthesis method for the stationary part of voiced-sounds. The method is based on a new class of wavelets, the Harmonic-Band Wavelets (HBWT). Wavelets have been widely employed in signal processing [1, 2]. In the context of sound processing they provided very interesting results in their first harmonic version: the Pitch Synchronous W...

If algebraic varieties like curves or surfaces are to be manipulated by computers, it is essential to be able to represent these geometric objects in an appropriate way. For some applications an implicit representation by algebraic equations is desirable, whereas for others an explicit or parametric representation is more suitable. Therefore, transformation algorithms from one representation to...

The skeleton, or medial axis, is an important attribute of 2-D shapes. disk B-spline curve (DBSC) a skeleton-based parametric freeform region representation, which defined in the form. DBSC describes not only region, suitable for describing heterogeneous materials but also center (skeleton) explicitly, animation, simulation, and recognition. In addition to being useful error estimation curve, c...
