Motion tracking and object segmentation are the most fundamental and critical problems in vision tasks such as motion analysis. An active contour model, snake, was developed as a useful segmenting and tracking tool for rigid or non-rigid objects. In this paper, the development of new snake model called “adaptive color snake model (ACSM)” for segmentation(More)
The ability to walk without the help of a caretaker enhances the quality of life for those who are bed-ridden or confined to a wheelchair. At present, most of the available gait rehabilitation robot systems have been designed to support the body weight externally. For gait training to be effective, a mobile body weight support (BWS) mechanism is needed. In(More)
In this paper, an intelligent bed robot system (IBRS) is proposed, that is a special bed equipped with robot manipulator. To assist a patient using IBRS, pose and motion estimation process is fundamental. It is designed to help the elderly and the disabled for their independent life in bed without other assistants
An intelligent bed robot system (IBRS) is proposed to help the elderly and the disabled for their independent life in bed. The IBRS is a special bed equipped with two robot arms and an array of pressure sensors attached onto the mattress. The pressure distribution on the mattress is used to estimate the pose of the patient, and an appropriate assistance is(More)
Motion tracking and object segmentation are the most fundamental and critical problems in vision tasks such as motion analysis. An active contour model, snake, was developed as a useful segmenting and tracking tool for rigid or non-rigid objects. Snake is designed on the basis of snake energies. Segmenting and tracking can be executed successfully by energy(More)
Robotic gait rehabilitation devices enable efficient and convenient gait rehabilitation by mimicking the functions of physical theraphists. In manual gait rehabilitation training, physical theraphists have patients practice and memorize normal gait patterns by applying assistive torque to the patient's joint once the patient's gait deviates from the normal(More)
A power assisted gait rehabilitation robot system by which a patient who has difficulty in walking can exercise is proposed. Our developed system consists of a robotic manipulator which can adjust the height of the system according to the user and a mobile base with two-driving wheels. It is similar to the architecture of a mobile manipulator. The neural(More)
The application of the hybrid self-organizing fuzzy PID (SOF-PID) controller to a multi input multi output (MIMO) nonlinear biped robot is studied in this paper. The self-organizing-fuzzy PID controller was initially studied by H. B. Kazemian but actually his self-organizing-fuzzy PID controller has limits. The supervisory of the self-organizing-fuzzy PID(More)
