Combining region-based and imprecise boundary-based cues for interactive medical image segmentation.
An approach combining both region selection and user point selection for user-assisted segmentation as either an enclosed object or an open curve is presented, which allows efficient and effective interactive segmentation, which can be used with both open and closed curves to segment a variety of images in different ways.

Minimum S-Excess Graph for Segmenting and Tracking Multiple Borders with HMM
A novel HMM based approach to simultaneous segmentation of vessel walls in Lymphatic confocal images by transforming the segmentation problem into a minimization of an s-excess graph cost, with each node in the graph corresponding to a hidden state and the weight for each node being defined by its emission probability. Expand
Interactive Segmentation of Media-Adventitia Border in IVUS
It is shown that this combined approach allows efficient and effective interactive segmentation, which is demonstrated through iden- tifying media-adventitia border in IVUS images where image artifact, such as acoustic shadow and calcification, are common place. Expand
Graph Based Lymphatic Vessel Wall Localisation and Tracking
Qualitative and quantitative analysis of the proposed hidden Markov model (HMM) based approach to segment and track the lymph vessel in confocal microscopy images show superior performance compared to the traditional Viterbi algorithm. Expand
Automatic segmentation of lymph vessel wall using optimal surface graph cut and hidden Markov Models
A novel method to segment the lymph vessel wall in confocal microscopy images using Optimal Surface Segmentation (OSS) and hidden Markov Models (HMM), which can be found in polynomial time. Expand
Coupled s-excess HMM for vessel border tracking and segmentation.
A novel image segmentation technique, based on hidden Markov model (HMM), which is applied to simultaneously segment interior and exterior walls of fluorescent confocal images of lymphatic vessels and is compared to the Viterbi and Baum-Welch algorithms. Expand
Code List Library: A Solution to Improve Research Repeatability, Transparency, and Efficiency by Curating Lists of Clinical Codes
A web application using Python and PostgreSQL that allows creating, editing, and accessing via a GUI, as well as a REST API for integration into SQL, R, and other environments to allow easier creation of code lists, for less technical users. Expand
2D and 3D segmentation of medical images
Interactive 3D Segmentation of Lymphatic Valves in Confocal Microscopic Images
A user informed, layer based segmentation framework is used to segment the outer boundary of the lymph valve in 3D from a series of confocal images, which creates a point cloud of voxels on the surface of the valve structure and is applied to reconstruct it as a continuous surface. Expand
