Development of a Heart Motion Tracking System using Non-invasive Imaging Data
Tucker, Bryent (East Carolina University, 2017-07-18)Cardiac motion can be monitored non-invasively for the assessment of cardiovascular function by using medical imaging systems and motion tracking algorithms. Existing tracking approaches require a priori understanding of ... -
Enhancing GNSS RTK Solutions with Random Sample Consensus
Krebs, Angela (East Carolina University, 2022-07-12)Precise positioning with Global Navigation Satellite Systems (GNSS) can be achieved by using the real-time kinematic (RTK) solution. A GNSS RTK solution was improved using an innovative approach based on Random Sample ... -

LOW-COST PHOTOGRAMMETRY SYSTEM FOR GEOREFERENCED STRUCTURE FROM MOTION
Hill, Nicholas (East Carolina University, 2022-07-21)Photogrammetry has become increasingly available as a tool for re-constructing the 3D model of real-world objects and terrain, which is referred to as the structure from motion (SFM) solution. The re-constructed model has ... -

Machine Learning Assisted Non-Rigid Surface Tracking in Biological Systems
Hempstead, William Henry (East Carolina University, 8/5/2020)Occlusions, obstructions, and lighting changes that occur in a camera's field-of-view (FOV) during a medical procedure can cause tracking algorithms to lose track of a particular region-of-interest (ROI). Various approaches ... -
Using Random Sampling Consensus (RANSAC) to Detect Errors in Global Navigation Satellite Systems (GNSS) Signals and Data
Shah, Nihar (East Carolina University, 2021-12-03)A positioning, navigation, and timing (PNT) signal can be used to estimate a user's position at an identified time. A global navigation satellite system (GNSS) uses the PNT signal to provide satellite-based navigation. ...
