Ambiguity is present in all types of images.

How do experts resolve ambiguities in interpretation of 3D imaging?

HCI Research: Data Segmentation

Prof. Ruth West (University of North Texas), is engaged in collaborative research with Prof. Cindy Grimm (Oregon State Univserity) and Prof. Tao Ju (Washington University St. Louis) to study the cognitive and perceptual basis of how experts extract 3D shapes from volumetric data, such as electron tomography, MRI or CT imaging. This process, known as “segmentation” plays an essential role in the interpretation and analysis of volume data in a variety of application domains.

Understanding what a segmenter sees, thinks, and does while interacting with a data set will help to make future tools more efficient, alleviating the major scientific bottleneck posed by the time-intensive nature of segmentation. It will also help in developing better tools to improve the accuracy and repeatability of the segmentation process, positively enhancing the quality of the resulting data for use in a variety of  applications, including biomedicine, clinical practice and environmental engineering.

  1. Segmentation Team Publishes at ACMs Applied Perception Symposium

    The 3D Segmentation team published their fourth paper, “How experts’ mental models affects 3D image segmentation” at ACM’s Symposium on Applied Perception (SAP), held July 22-23, 2016 in Anaheim, California. The ACM published the paper to the SAP ’16  proceedings. The paper outlines the research design of the following hypothesis: Provided with a 3D structure and slicing plane experts are able to predict the 2D contour, how 2D contour changes with small view changes...
  2. Segmentation Team Publishes at Vinci 2016

    The 3D Segmentation team presented their third paper this year, “Eliciting Tacit Expertise in 3D Volume Segmentation” at the 2016 Symposium on Visual Information Communication and Interaction (VINCI), held Sept.24-26 in Dallas, Texas. The ACM published the paper to the VINCI 2016 symposium proceedings. The paper examines manual (semi-automatic), low-level (perceptual) and high-level decision making by experts dealing with 3D data. The analaysis hopes to provide valuable information used to design more accurate, efficient, easier...
