Fall detection based on shape deformation
WebFall detection methods are subdivided into two classes: computer vision-based methods and non-computer vision method. In this section, we will review some works proposed for fall detection starting by non-vision category. Many sensors have been exploited. WebMar 25, 2016 · Abstract: This paper addresses issues in fall detection from RGB-D videos. The study focuses on measuring the dynamics of shape and motion of the target person, based on the observation that a fall usually causes drastic large shape deformation and physical movement.

WebWu developed a new fall detection system based on wearable devices. The fall is identified by an effective quaternion-based algorithm and a help request is automatically sent to the patient’s location (Wu, Zhao, Zhao, & Zhong, Citation2015). However, there are some shortcomings of this system. WebJul 11, 2024 · Fall Detection uses an accelerometer inside your medical alert pendant. This senses a fall and connects you to a highly trained emergency response operator even if …
WebDec 7, 2014 · In this paper we present a novel fall detection system using both accelerometers and gyroscopes. We divide human activities into two categories: static postures and dynamic transitions. By using two tri-axial accelerometers at separate body locations, our system can recognize four kinds of static postures: standing, bending, … WebNov 1, 2024 · In this paper, a new vision-based method for fall detection is proposed to allow older people to live independently and safely. The proposed method uses shape …
WebMay 14, 2014 · Based on these observation, we propose a new monocular vision-based fall detection method in this paper. An efficient moving object detection method is applied to extract the foreground human silhouette. Then, a set of features from the ellipse-fitted silhouette are used for quantizing the shape deformation of the human body. WebFall detection algorithms can be divided into three categories: threshold-based, machine learning-based and deep learning-based methods. 2.1.1. Threshold The threshold method is the earliest proposed algorithm for fall detection. …
