This paper addresses the issue in scenario-based understanding of human behavior from videos in a nursing care monitoring system. The analysis is carried out based on experiments consisting of single-state scenarios and multi-state scenarios where the former monitors activities under contextual contexts for elementary behavior reasoning, while the latter dictating the elementary behavior order ...

Often people attempt to live their lives backwards; they try to have more things, or want more money, in order to do more of what they want, so they will be happier. The way it actually works is the reverse. You must first be who you really are, then do what you need to do, in order to have what you want.

It is well known that decreased standing balance increases the risk of falling, and it has also been reported to reduce everyday activity and be linked to disuse syndrome [1]. A previous study had shown that even among elderly people, the standing balance stability of a group who had a fall was significantly lower than that in a non-fall group [2]. Thus, an elderly person’s ability to maintain ...

Attention is a factor that affects the performance of various intelligent activities in humans. Up until now, the methods for measuring the level of attention have been mostly based on subjective reports or employing large and costly devices. In this paper, a new method of estimating the level of attention is proposed, based on posture and EEG measurements. These data can be recorded using easi...

We present a trainable system for locating clothed people in photographic images. People detection is a particularly challenging image understanding problem; as a result of variations in clothing and posture, the appearance of people may vary enormously from image to image. Our approach attempts to construct a maximally personlike assembly of image regions, where candidate regions are provided ...

This paper proposes a method for the rapid and precise estimation of human hand postures by combining 2-D appearance matching and 3-D model-based fitting. First a rough posture estimate is obtained by image indexing. Each possible hand appearance generated from a given 3-D shape model is labeled by an index obtained by PCA compression and registered with its 3-D model parameters in advance. By ...

The entire business landscape finds itself on the verge of a recession because of ongoing global economic turmoil. Thus, there is a heightened need to minimise and mitigate business risk and scrutinise information spending while ensuring compliance with regulatory mandates. This calls for decision makers to become vigilant in their spending and move towards an optimised information security inv...

In the most general case the measurement of the links lengths of a 6 d.o.f parallel manipulator is not sufficient to determine the actual unique posture of its platform. We investigate how this posture can be determined by adding sensors to the manipulator. We show that by adding four sensors on the passive joints a unique closed-form solution of the posture of the endeffector can be obtained f...

This article analyzes a set of methods for processing images of people for skin segmentation. The Jochen Triesch Static Hand Posture Database [9] provides a wide range of skin tones obtained from people of different ages and breeds. The skin detection task on images give face to distinct challenges, due to various factors like: ilumination variations, environment factors and background. In this...

Mobile robots have been adopted to repair failed wireless sensor network systems for node damage, battery exhaustion, or obstacles. But most of the robots use wheeled locomotion manner, which does not work well or even fails when confronted with obstacles in uneven terrains. To solve this problem, this paper presents the design of a jumping robot to serve as a robotic node for wireless sensor n...
