Recently 3D volumetric organ segmentation attracts much research interest in medical image analysis due to its significance in com- puter aided diagnosis. This paper aims to address the pancreas segmen- tation task in 3D computed tomography volumes. …
We introduce a new multi-dimensional nonlinear embedding, Piecewise Flat Embedding (PFE), for image segmentation. Based on the theory of sparse signal recovery, piecewise flat embedding with diverse channels attempts to recover a piecewise constant …
Image segmentation is a critical step in many computer vision tasks, including high-level visual recognition and scene understanding as well as low-level photo and video processing. In this paper, we propose a new nonlinear embedding, called …
