The book presents a unique overview of recent as well as traditional image enhancement methods. We have demonstrated practical examples of frequency domain image enhancement techniques. Most of the book is related to 2D images but generalization to 3D is also shown in most cases. Automatic object recognition has become an established discipline inside image analysis. Moments and moment invariants play a very important role as features in invariant recognition. Our main purpose in writing this book was to bridge this gap between theoretical concepts and practical implementations of image...

The establishment of the clinical electrocardiograph (ECG) by the Dutch physician Willem Einthoven in 1903 marked the beginning of a new era in medical diagnostic techniques, including the entry of electronics into health care. Since then, electronics, and subsequently computers, have become integral components of biomedical signal analysis systems, performing a variety of tasks from data acquisition and preprocessing for removal of artifacts to feature extraction and interpretation. The clinically relevant information in the signal is often masked by noise and interference, and the signal...

A mobile ad hoc network is a collection of wireless nodes that can dynamically be set up anywhere and anytime without using any pre-existing network infrastructure. Ad hoc networking can be applied anywhere where, there is little or no communication infrastructure or the existing infrastructure is expensive or inconvenient to use. One of the motivation behind this activity is the need felt by people to communicate with computers or device in natural mode of communication in respect of diverse application. The book is an attempt to present the advances in the networking technology -both theory...
