Real Time Tracking

A method for real-time automatic tracking of the left ventricle (LV) in 3D ultrasound is presented. A mesh model of the LV is deformed using mean value coordinates enabling large variations. Kalman filtering and edge detection is used to track the mesh in each frame. The method is evaluated using the framework of the Challenge on Endocardial Three-dimensional Ultrasound Segmentation (CETUS). The results show that the method is able to robustly track the LV in all sequences with a mean mesh difference of about 2.5 mm

Warehouse Management System

A warehouse management system using the three-dimensional location tracking and positioning system based on time-of-flight principle is presented in this paper. Integrating three distance measurement sensors and computer programming to process the signals obtained from the sensors, the system can capture, store, and retrieve the three-dimensional position of steel coils located in a warehouse in real time. Updated information will also be stored in a database as a backup. Experiment shows that the system designed in this paper has the merits of real-time tracking of steel coils stored in a warehouse, or any uniformed storage locations.
