Sift-Me: A New Feature For Human Activity Recognition, Guosheng Wu
Sift-Me: A New Feature For Human Activity Recognition, Guosheng Wu
Electronic Theses and Dissertations
Action representation for robust human activity recognition is still a challenging problem. This thesis proposed a new feature for human activity recognition named SIFT-Motion Estimation (SIFT-ME). SIFT-ME is derived from SIFT correspondences in a sequence of video frames and adds tracking information to describe human body motion. This feature is an extension of SIFT and is used to represent both translation and rotation in plane rotation for the key features. Compare with other features, SIFT-ME is new as it uses rotation of key features to describe action and it robust to the environment changes. Because SIFT-ME is derived from SIFT …
Toward A Distributed Actuation And Cognition Means For A Miniature Soft Robot, Xiaoting Yang
Toward A Distributed Actuation And Cognition Means For A Miniature Soft Robot, Xiaoting Yang
Electronic Theses and Dissertations
This thesis presents components of an on-going research project aimed towards developing a miniature soft robot for urban search and rescue (USAR). The three significant contributions of the thesis are verifying the water hammer actuation previous work, developing an estimator of water hammer impulse direction from hose shape, and creating the infrastructure for distributed cognitive networks. There are many technical issues in designing soft robots, in terms of perception, actuation, cognition, power, physical structure and so on. We are focusing on actuation and cognition issues in this thesis. We investigated water hammer actuation as an alternative system which provides a …
Analysis And Design Of A Feedback Controlled Adaptive Pneumatic Cast, Susan Renee Mueller
Analysis And Design Of A Feedback Controlled Adaptive Pneumatic Cast, Susan Renee Mueller
Electronic Theses and Dissertations
A pneumatic system with PID control for an actively controlled cast is designed. The cast is intended to aid healing of diabetic foot ulcers by relieving pressure from the sole of a patient's foot and distributing it to the calf. This is accomplished by a pneumatic system which maintains set pressure in multiple air bladders. The research began by defining an electrical circuit analogous to a single supply subsystem. Tests are performed to determine the coefficients for each component. These coefficients are used in a mathematical model to better understand the response of the system to pressure input. A controller …
