Statistical Personal Tracker
نویسنده
چکیده
Tracking people using movie sequences is not straightforward because the human body is articulated (and therefore far from rigid), parts of the body are frequently occluded by other parts, and video data is inevitably degraded by noise. In this paper we show how a person’s 3D pose can be tracked by using corresponding silhouette moments from video sequences. The moment computation has been implemented in real-time for real data and shown to work satisfactorily for data obtained in the laboratory or a dance studio or theatre. Currently, a virtual avatar is used to train the model for inferring the pose and a different avatar is used to produce novel examples not in the training set in order to evaluate this approach.

Step Towards Better Security: Attacks and Defenses for Low Power Fitness Trackers
Wearable personal fitness trackers automatically collect sensor data about the user throughout the day and integrate this data into social network accounts. The increasing popular interest in personal telemetry, also called the Quantified Self or ‘‘lifelogging’’, has induced this flourishing new product category. The makers of these trackers have to strike a balance between many constraints inc...
متن کاملStatistical chromaticity-based lip tracking with B-splines
We present a statistical, colour-based technique for lip tracking intended to support personal veri cation. The lips are automatically localised in the original image by exploiting grey-level gradient projections as well as chromaticity models to nd the mouth area in an automatically segmented region corresponding to the face area. A B-spline, initially with an elliptic shape is then generated ...
متن کاملVisual tracking of hands, faces and facial features as a basis for human-robot communication
This paper presents an integrated approach for tracking hands, faces and specific facial features (eyes, nose, and mouth) of multiple persons in image sequences. For hand and face tracking, we employ a state-of-the-art blob tracker which is specifically trained to track skin-colored regions. The skin-color tracker is extended by incorporating an incremental probabilistic classifier used to main...

متن کاملA new fuzzy-based maximum power point tracker for photovoltaic applications
A new fuzzy maximum power point tracker (MPPT) for photovoltaic systems is proposed. Fuzzy controller input parameters dI dP , ) dI dP ( D and variation of duty cycle ( DC D ) are used to generate the optimal MPPT converter duty cycle, such that solar panel maximum power is generated under different operating conditions. A photovoltaic system including a solar panel, a fuzzy MPP tracker and...
