Wavelet methods have become a widely spread tool in signal and image process ing tasks. This book deals with statistical applications, especially wavelet based smoothing. The methods described in this text are examples of non-linear and non parametric curve fitting. The book aims to contribute to the field both among statis ticians and in the application oriented world (including but not limited to signals and images). Although it also contains extensive analyses of some existing methods, it has no intention whatsoever to be a complete overview of the field: the text would show too much bias towards my own algorithms. I rather present new material and own insights in the questions involved with wavelet based noise reduction. On the other hand, the presented material does cover a whole range of methodologies, and in that sense, the book may serve as an introduction into the domain of wavelet smoothing. Throughout the text, three main properties show up ever again: sparsity, locality and multiresolution. Nearly all wavelet based methods exploit at least one of these properties in some or the other way. These notes present research results of the Belgian Programme on Interuniver sity Poles of Attraction, initiated by the Belgian State, Prime Minister's Office for Science, Technology and Culture. The scientific responsibility rests with me. My research was financed by a grant (1995 - 1999) from the Flemish Institute for the Promotion of Scientific and Technological Research in the Industry (IWT).

The Mixtec, or the people of Ñuu Savi ('Nation of the Rain God'), one of the major civilizations of ancient Mesoamerica, made their home in the highlands of Oaxaca, where they resisted both Aztec military expansion and the Spanish conquest. In Encounter with the Plumed Serpent, two leading scholars present and interpret the sacred histories narrated in the Mixtec codices, the largest surviving collection of pre-Columbian manuscripts in existence. In these screenfold books, ancient painter-historians chronicled the politics of the Mixtec from approximately a.d. 900 to 1521, portraying the royal families, rituals, wars, alliances, and ideology of the times. By analyzing and cross-referencing the codices, which have been fragmented and dispersed in far-flung archives, the authors attempt to reconstruct Mixtec history. Their synthesis here builds on long examination of the ancient manuscripts. Adding useful interpretation and commentary, Jansen and Pérez Jiménez synthesize the large body of surviving documents into the first unified narrative of Mixtec sacred history. Archaeologists and other scholars as well as readers with an interest in Mesoamerican cultures will find this lavishly illustrated volume a compelling and fascinating history and a major step forward in knowledge of the Mixtec.

Wavelets from a Statistical Perspective

Wavelets from a Statistical Perspective offers a modern, 2nd generation look on wavelets, far beyond the rigid setting of the equispaced, dyadic wavelets in the early days. With the methods of this book, based on the lifting scheme, researchers can set up a wavelet or another multiresolution analysis adapted to their data, ranging from images to scattered data or other irregularly spaced observations. Whereas classical wavelets stand a bit apart from other nonparametric methods, this book adds a multiscale touch to your spline, kernel or local polynomial smoothing procedure, thereby extending its applicability to nonlinear, nonparametric processing for piecewise smooth data. 
One of the chapters of the book constructs B-spline wavelets on nonequispaced knots and multiscale local polynomial transforms. In another chapter, the link between wavelets and Fourier analysis, ubiquitous in the classical approach, is explained, but without being inevitable. In further chapters the discrete wavelet transform is contrasted with the continuous version, the nondecimated (or maximal overlap) transform taking an intermediate position. An important principle in designing a wavelet analysis through the lifting scheme is finding the right balance between bias and variance. Bias and variance also play a crucial role in the nonparametric smoothing in a wavelet framework, in finding well working thresholds or other smoothing parameters. The numerous illustrations can be reproduced with the online available, accompanying software. The software and the exercises can also be used as a starting point in the further exploration of the material.

Painted shortly before the Spanish conquest of Mexico in 1521, the Codex Bodley has been long recognized as one of the most important Mixtec manuscripts and a premier example of native Mixtec pictorial historiography in all its complexity. The complete manuscript of the Codex Bodley is offered here for the very first time in a single illustrated volume. Codex Bodley explores the enormous wealth of information contained in the manuscript, which documents precolonial Mixtec genealogical relationships and historical events spanning from 900 AD to 1521. Maarten Jansen and Gabina Aurora Pérez Jiménez provide insightful and expert commentary on the manuscript, explaining its history as they consider key characteristics of Mixtec pictography. They then provide an engaging and masterful interpretation of the manuscript's narrative, with a detailed explanatory reading of its pictograms and their significance. Accompanied by vivid and colorful illustrations, Codex Bodley is an invaluable text for scholars of precolonial Mexican history, art, and culture.

In Time and the Ancestors: Aztec and Mixtec Ritual Art, Maarten Jansen and Aurora Pérez present new interpretations of enigmatic masterpieces from ancient Mexico. Combining iconographical analysis with the study of archaeological contexts, historical sources and living cultural traditions, they shed light on central symbols and values of the religious heritage of indigenous peoples, paying special attention to precolonial perceptions of time and the importance of ancestor worship. They decipher the meaning of the treasure deposited in Tomb 7 at Monte Albán (Oaxaca) and of artworks such as the Roll of the New Fire (Selden Roll), the Aztec religious sculptures and, last but not least, the mysterious chapter of temple scenes from the Book of Night and Wind (Codex Borgia).
