AB  - Subject movement and a dark environment will increase the difficulty of 
      image-based contactless pulse rate detection. In this paper, we detected the 
      subject's motion status based on complexion tracking and proposed a motion index 
      (MI) to filter motion artifacts in order to increase pulse rate measurement 
      accuracy. Additionally, we integrated the near infrared (NIR) LEDs with the 
      adopted sensor and proposed an effective method to measure the pulse rate in a 
      dark environment. To achieve real-time data processing, the proposed framework is 
      constructed on a Field Programmable Gate Array (FPGA) platform. Next, the instant 
      pulse rate and motion status are transmitted to a smartphone for remote 
      monitoring. The experiment results showed the error of the pulse rate detection 
      to be within -3.44 to +4.53 bpm under sufficient ambient light and -2.96 to + 
      4.24 bpm for night mode detection, when the moving speed is higher than 14.45 
      cm/s. These results demonstrate that the proposed method can improve the 
      robustness of image-based contactless pulse rate detection despite subject 
      movement and a dark environment.
