This software is designed as a learning and experimentation tool (rather than for use in solving high-precision computational problems), and offers users hands-on practice in the area of wavelet analysis and its applications. It supports several different wavelets, and contains, among other algorithms and codes, the one-dimensional and two-dimensional discrete wavelet transforms and their inverse transforms, as well as computations of the continuous wavelet transform and the short time Fourier transform. Simple signal processing applications, such as thresholding and noise removal are also included as examples of how to use the software. Annotation c. by Book News, Inc., Portland, Or.

Wavelet Subdivision Methods: GEMS for Rendering Curves and Surfaces

Prevalent in animation movies and interactive games, subdivision methods allow users to design and implement simple but efficient schemes for rendering curves and surfaces. Adding to the current subdivision toolbox, Wavelet Subdivision Methods: GEMS for Rendering Curves and Surfaces introduces geometry editing and manipulation schemes (GEMS) and covers both subdivision and wavelet analysis for generating and editing parametric curves and surfaces of desirable geometric shapes. The authors develop a complete constructive theory and effective algorithms to derive synthesis wavelets with minimum support and any desirable order of vanishing moments, along with decomposition filters.\nThrough numerous examples, the book shows how to represent curves and construct convergent subdivision schemes. It comprehensively details subdivision schemes for parametric curve rendering, offering complete algorithms for implementation and theoretical development as well as detailed examples of the most commonly used schemes for rendering both open and closed curves. It also develops an existence and regularity theory for the interpolatory scaling function and extends cardinal B-splines to box splines for surface subdivision.\nKeeping mathematical derivations at an elementary level without sacrificing mathematical rigor, this book shows how to apply bottom-up wavelet algorithms to curve and surface editing. It offers an accessible approach to subdivision methods that integrates the techniques and algorithms of bottom-up wavelets.
