Home Camera-Based Fall Detection System for the Elderly

Abstract: Falls are the leading cause of injury and death in elderly individuals. Unfortunately, fall detectors are typically based on wearable devices, and the elderly often forget to wear them. In addition, fall detectors based on artificial vision are not yet available on the market. In this paper, we present a new low-cost fall detector for smart homes based on artificial vision algorithms. Our detector combines several algorithms (background subtraction, Kalman filtering and optical flow) as input to a machine lear… Show more

“…Computer vision-based motion detection takes a video of a person’s motion with an optical camera and uses advanced image processing algorithms to determine whether there is a frame with a motion feature to detect [ 18 ]. De Miguel et al developed a fall detection system based on a camera for the elderly that applies various algorithms to extract better features and used a K-nearest neighbors algorithm to achieve recognition [ 19 ]. Yu et al used an enhanced one-class support vector machine as a recognition algorithm and obtained features including the differences of barycenter position and orientation of a person over a time period as input [ 20 ].…”

“…The model developed by the authors consists of an algorithm to detect when a person is in the frame and a posture recognition algorithm to detect movements associated with falls that occur during the performance of sitting down and standing up movements. De Miguel et al [ 11 ] combined algorithms, ranging from Kalman filtering to optical flow analysis, with an algorithm designed for artificial vision. When a fall occurs, the system detects the event and sends an alarm notification message along with a picture to the caregiver.…”

“…The authors in (Gunale and Mukherji, 2015) proposed a system for patient monitoring based on KNN classification and the ratio of the fitted ellipse, orientation angle, silhouette threshold and motion coefficient as visual descriptors. The researchers in (de Miguel et al, 2017) proposed an elderly fall detection system which mainly subtracts the object (human body) from the frame background using standard background subtraction technique. Note that the ratio and angle of the bounding box contouring the human body and the ratio derivative are used as visual descriptors.…”
