Human Movement Analysis: Ballistic Dynamics, and Edge Continuity for Pose Estimation
… (b) a model for coupling edge continuity with contour matching. We describe a Bayesian approach for visual analysis of ballistic hand movements, namely reaches and strikes. These movements are most commonly used for interacting with objects and the environment. One of the key challenges to …

Terrain relative localization for lunar entry, descent, and landing
… is terrain relative localization, which entails matching a sensor image of the planetary surface to the stored map of the surface. This correlation allows a position match to be determined, which is used to update the spacecraft's inertial navigation system. This thesis focuses upon two terrain …

Image analysis using visual saliency with applications in hazmat sign detection and recognition
… and then use a Fourier descriptor based contour matching method to locate the border of hazmat signs in these regions. This visual saliency based approach is able to increase the accuracy of sign location detection, reduce the number of false positive objects, and speed up the overall …

A deep learning algorithm for contour detection in synthetic 2D biplanar X-ray images of the scapula: towards improved 3D reconstruction of the scapula
… The literature shows that detection and use of contours to locate corresponding landmarks within biplanar X-ray images can address this limitation. The aim of this research project was to train and validate a deep learning algorithm for detection the contour of a scapula in synthetic 2D …

Local Adaptive Slicing for Layered Manufacturing
Existing layered manufacturing systems fabricate parts using a constant build layer thickness. Hence, operators must compromise between rapid production with large surface inaccuracies, and slow production with high precision, by choosing between thick and thin build layers, respectively. Adaptive …
