To usher in a new era of Precision Medicine, imaging is playing an increasingly significant role, with its superior capability of phenotyping the physical manifestations of disease. Meanwhile, this opportunity poses the great challenge of enhancing image processing technology to meet the new demands. Robust, efficient, and accurate automated image segmentation is an indispensable step towards quantitative image analysis. In this talk, we present effective image segmentation methods to optimally identify the boundary surfaces of the target objects, based on enabling graph algorithms and emerging deep learning. Our model-based deep-learning (MoDL) framework for image segmentation unifies the strengths of both deep learning and the graph-based surface segmentation model in a single framework while minimizing their respective limitations. The novel feature of our method is designed with a focus on the global optimality of the segmentation solutions. Examples and segmentation results on various medical image datasets will be shown.
