An original reference applying wavelet analysis to power systems engineering

- Introduces a modern signal processing method called wavelet analysis, and more importantly, its applications to power system fault detection and protection
- Concentrates on its application to the power system, offering great potential for fault detection and protection
- Presents applications, examples, and case studies, together with the latest research findings
- Provides a combination of the author's tutorial notes from electrical engineering courses together with his own...

he problem of analyzing sequences of images to extract three-dimensional T motion and structure has been at the heart of the research in computer vi sion for many years. It is very important since its success or failure will determine whether or not vision can be used as a sensory process in reactive systems. The considerable research interest in this field has been motivated at least by the following two points: 1. The redundancy of information contained in time-varying images can over come several difficulties encountered in interpreting a single image. 2. There are a lot of important...

This volume treats the analysis of 3D dynamic scenes using a stereovision system. Several approaches are described, for example two different methods of dealing with long and short sequences of images of an unknown environment, including an arbitrary number of rigid mobile objects. Results obtained from stereovision systems are found to be superior to those from monocular image systems, which are often very sensitive to noise and therefore of little use in practice. It is shown that motion estimation can be further improved by the explicit modelling of uncertainty in geometric objects. The...
