Hi Geesara, I used Haar full body cascade and HoG pedestrian detection cascade, In Haar full body cascade they have mentioned that, upper body detection, lower body detection and full body detection is there in the cascade. even thought it is there, once I tried to use separate upper body detection cascade with full body detection cascade. but when it is implemented system took long time to process even a simple video with two person. I'll upload my code to Github repo. I still didn't work with real-time CCTV videos ,but I was able to build a real-time face detection system using the web cam of my laptop and it had issues on processing as the machine couldn't handle it. We thought of doing video processing out side of the CEP and send the process data in to the CEP.(i.e human count, time_stamp, frame rate ,etc..). For now I send those data into CEP as a Json POST request.
