The first book to serve as a comprehensive review of digital imaging and computer vision with graphs, this reference helps readers unfamiliar with presented concepts. The book is divided into two parts that focus on the processing of functions on graphs, graph-based image processing, representation and analysis of objects on graphs, and graph-based image analysis. Each chapter provides a comprehensive review on a specific topic. These range from research challenges to industry trends, and contributors provide numerous examples to illustrate how the proposed methods can be used in practice. A companion website is available.
