Fall detection using multimodal data
This work addresses fall detection to improve safety for older adults, but it appears incremental as it builds on existing datasets and methods.
The paper tackled fall detection for older adults by proposing techniques to extract features from multimodal sensor and camera data, achieving state-of-the-art results in accuracy, precision, recall, and F1 score on the UP-Fall Detection Dataset.
In recent years, the occurrence of falls has increased and has had detrimental effects on older adults. Therefore, various machine learning approaches and datasets have been introduced to construct an efficient fall detection algorithm for the social community. This paper studies the fall detection problem based on a large public dataset, namely the UP-Fall Detection Dataset. This dataset was collected from a dozen of volunteers using different sensors and two cameras. We propose several techniques to obtain valuable features from these sensors and cameras and then construct suitable models for the main problem. The experimental results show that our proposed methods can bypass the state-of-the-art methods on this dataset in terms of accuracy, precision, recall, and F1 score.
