Algorithm 1 Pseudo-Code for visitor detection from a video streaming source

1: Read CCTV video stream file 2: Set frame as video frame at time T, where T is the last epoch 3: Set scale as 1.05 for optimum human figure detection 4: Set group threshold as 1to detect each individual in frame 5: Detect and draw detection rectangles over identified human figures 6: for rectangle in detection rectangles of a frame 7:   Set X as x coordinate of top, left vertex of the rectangle 8:   Set Y as y coordinate top, left vertex of the rectangle 9:   Set width as width of the rectangle 10: Set height as height of the rectangle recommendations 11: Set center_x as X + width/2 12: Set center_y as Y + height/2 13: Save center_x, center_yin CSV files //the CSV files will be read by Popularity estimation module 14: end for
