This book is an introduction to level set methods, which are powerful
numerical techniques for analysing and computing interface motion in a
host of settings. They rely on a fundamental shift in how one views
moving boundaries; rethinking the natural geometric Lagrangian
perspective and exchanging it for an Eulerian, initial value partial
differential equation perspective. The resulting numerical techniques
can be used to track three-dimensional complex fronts that can develop
sharp corners and change topology as they evolve. A large collection of
applications is provided in the text, including examples from physics,
chemistry, fluid mechanics, combustion, image processing, material
science, fabrication of microelectronic components, computer vision and
control theory. This book will be a useful resource for mathematicians,
applied scientists, practising engineers, computer graphic artists, and
anyone interested in the evolution of boundaries and interfaces.
