Identifying medicine bottles by incorporating RFID and video analysis

Abstract

In this paper, we present a new framework of identifying medicine bottles using a combination of a video camera and Radio Frequency Identification (RFID) sensors for applications of monitoring the elderly's activities of daily living (ADLs) at home. RFID tags are attached to medicine bottles and first detected by RFID readers from the antenna. However, the RFID detection can only detect RFID tags within a certain range of the antenna. Once a medicine bottle is moved out of the range of the RFID antenna, a camera will be activated to continue detecting and tracking the medicine bottle for further action analysis based on moving object detection and color model of the medicine bottle. The experimental results demonstrate 100% detection accuracy for identifying medicine bottles.
