This book provides a comprehensive review of precoding techniques for digital communications systems from a signal processing perspective. In the first part of the book the authors provide an overview of the principles of precoding for channels with intersymbol interference (ISI) such as Tomlinson-Harashima precoding and Trellis precoding. There is also a discussion on how the widely used OFDM systems can be treated as a special case of precoding techniques and introduce precoding schemes for OFDM systems. Further, the book provides an overview of various existing precoding techniques that reduce the interference level while keeping the receiver design simple in CDMA systems. There is also a complete chapter on the issue of precoding for multiple input multiple output (MIMO) channels. The second part of the book introduces the state-of-the-art precoding techniques originating from several projects and research activities involving multiuser OFDM transmissions and ultra-wideband (UWB) radio systems.

This book focuses on interactive segmentation techniques, which have been extensively studied in recent decades. Interactive segmentation emphasizes clear extraction of objects of interest, whose locations are roughly indicated by human interactions based on high level perception. This book will first introduce classic graph-cut segmentation algorithms and then discuss state-of-the-art techniques, including graph matching methods, region merging and label propagation, clustering methods, and segmentation methods based on edge detection. A comparative analysis of these methods will be provided with quantitative and qualitative performance evaluation, which will be illustrated using natural and synthetic images. Also, extensive statistical performance comparisons will be made. Pros and cons of these interactive segmentation methods will be pointed out, and their applications will be discussed. There have been only a few surveys on interactive segmentation techniques, and those surveys do not cover recent state-of-the art techniques. By providing comprehensive up-to-date survey on the fast developing topic and the performance evaluation, this book can help readers learn interactive segmentation techniques quickly and thoroughly.
