Both signal processing and image processing play increasingly important roles in remote sensing. Most data from satellites are in image forms; thus image processing has been used more often. However, signal processing can contribute significantly in extracting information from remotely sensed data. In contrast to other texts that focus on image processing, this book provides a balance between the two. Featuring contributions from worldwide experts that cover methodologies of both, each chapter presents a unique technique in addressing a specific remote sensing problem. Emphasizing mathematical approaches, this text also contains detailed descriptions various mathematical techniques.
