In almost all application areas where multidimensional data are acquired, some portion of the processing pipeline requires the identification and quantification of specific regions in the field of regard either as the ultimate solution to the underlying problems or as an intermediate step toward the extraction of higher level information. While many methods have been proposed in the last 30 years for solving such problems, here we concentrate on a flexible class of techniques that can be broadly applied across a range of application areas. Specifically, model-based methods as the foundation for variational (i.e., optimization) formulations of segmentation problems have found great favor both for problems where one is provided pixel-type data as well as for problems of a tomographic nature where indirect measurements of the scene are the basis for processing. In this talk we discuss the basic ideas underlying this approach to segmentation and consider in some depth how these methods are employed for a number of problems in the areas of optical tomography, microscopy, and environmental remediation.
