Summary: | The purpose of this study is to design a system that allows monitoring of the elderly
within their household at all times. The report consists of three stages for monitoring
– Human Detection, Human Posture Recognition, and Human Activity Recognition.
Human detection allows the system to detect the exact location of the elderly
whereas, posture recognition and activity recognition will determine the current
status of the elderly. Two postures – Standing and Lying, are recognized by the
system. By using the posture recognition algorithms, the system will classify the ongoing
activity based on the sequence of postures detected.
The system will be implemented with background subtraction and Histogram of
Oriented Gradients. Information retrieved from the subtracted background and the
classified posture will be used to classify the activity.
After testing the implemented system, a detection accuracy of 90% has been
achieved for human detection and an accuracy of 93% has been achieved for
standing posture detection. Although, an accuracy of only 28% has been achieved for
lying posture detection, the implemented system managed to detect falling activities
accurately.
Therefore, a conclusion can be drawn such that the current status of the elderly can
be monitored successfully using the implemented system. |
