چکیده

We propose a novel model-based approach to activity recognition using high-level primitives that are derived from a human body model estimated from sensor data. Using short but fixed positions of the hands and turning points of hand movements, a continuous data stream is segmented in short segments of interest. Within these segments, joint boosting enables the automatic discovery of important and distinctive features ranging from motion over posture to location. To demonstrate the feasibility of our approach we present the user-dependent and acrossuser results of a study with 8 participants. The specific scenario that we study is composed of 20 activities in quality inspection of a car production process.

Lightweight 4x4 MDS Matrices for Hardware-Oriented Cryptographic Primitives

Linear diffusion layer is an important part of lightweight block ciphers and hash functions. This paper presents an efficient class of lightweight 4x4 MDS matrices such that the implementation cost of them and their corresponding inverses are equal. The main target of the paper is hardware oriented cryptographic primitives and the implementation cost is measured in terms of the required number ...

A Sensor-Based Scheme for Activity Recognition in Smart Homes using Dempster-Shafer Theory of Evidence

This paper proposes a scheme for activity recognition in sensor based smart homes using Dempster-Shafer theory of evidence. In this work, opinion owners and their belief masses are constructed from sensors and employed in a single-layered inference architecture. The belief masses are calculated using beta probability distribution function. The frames of opinion owners are derived automatically ...

Activity Discovery from Occlusion Primitives

Complex multi-agent interactions result in occlusion sequences which are a visual signature for the event. In this work, multi-agent interactions are tracked using a set of qualitative occlusion primitives derived based on the Persistence Hypothesis (objects continue to exist even when hidden from view). Variable length temporal sequences of occlusion primitives are shown to be well-correlated ...

Identifying Important Action Primitives for High Level Activity Recognition

Smart homes have a user centered design that makes human activity as the most important type of context to adapt the environment according to people’s needs. Sensor systems that include a variety of ambient, vision based, and wearable sensors are used to collect and transmit data to reasoning algorithms to recognize human activities at different levels of abstraction. Despite various types of a...
