  22. 22. Conclusions<br />In this system, a simple image-based person to camera distance and human movement speed measuring system is proposed. <br />The proposed system is simple, cost effective and efficient for real-time implementation for human motion detection.<br />The overall accuracy of the person-to-camera distance measurement system is 94.11%.<br />
  23. 23. Human motion detection for video surveillance.<br />Accuracy measurement of the human motion detection and movement speed measurement.<br />Consideration of side face views and face rotation for improving the accuracy of measurement.<br />Human height and weight which influences the interocular distance needs to be addressed.<br />3-Dimensional interocular distance consideration for more robustness. <br />Future Directions<br />
