Abstract. We consider the problem of multi-label, supervised image segmentation when an initial labeling of some pixels is given. In this paper, we propose a new generative image segmentation algorithm for reliable multi-label segmentations in natural images. In contrast to most existing algorithms which focus on the
The random walker algorithm is an algorithm for image segmentation. In the first description of the algorithm, a user interactively labels a small number of pixels with known labels (called seeds), e.g., "object" and "background". The unlabeled pixels are each imagined to release a random walker, and the probability is
seeds. 2.1. Single image random walk segmentation. The diffusion probabilities are modeled using a ran- dom walk with restart (RWR) process. To define this process, let us first consider the simpler setting where an image I is segmented without using atlases. Suppose that I contains a set of labeled pixels xs ? S. In this.
