Abstract

We propose a framework for locally adaptive level set functions. The impact of well-known speed terms for the evolution of the active contour is adjusted by parameterising them with functions based on pre-defined properties. This allows for the application of level set methods even if image features are subject to large variations or if certain properties of the model are only valid for parts of the segmentation process. We present a number of examples and applications for the proposed concept and also address advantages and drawbacks of combinations of locally adaptive speed terms.
