Abstract :
In this paper, the authors present a method of generating a real-time threshold for each incoming image frame using the histogram concavity technique. A real-time histogram hardware unit is built to facilitate such approach. The system can determine the optimal threshold value once the frame is obtained, and it takes about 10 ms to work out this value
