Constant execution time multiple human detector regardless of target number increase based on HLAC

This paper proposes the constant execution time multiple human detection system. The human detection from video sequence is important in a monitoring camera system and a robot vision. It is important not to change the execution time in human detection system regardless number of persons. In this paper, the feature amount of an image was calculated by using Higher-Order Local Auto Correlation (HLAC) in video sequence. HLAC has position invariability and additivity. We verify the human detection rate and the execution time by the number of persons. We show the system do not change the execution time in multiple human detection.
