该课题为基于MATLAB的肤色的人数统计系统，以地铁车厢为实际背景，通过预测的方式，结合肤色统计人脸得到车厢人数，从而估计拥挤度，将结果反馈给车站里的视频，让乘客得知每节车厢的拥挤程度，从而合理分配车厢乘客，避免资源浪费和拥挤，本设计带有一个GUI交互界面。是一个人数统计类课题，该课题可以应用于教室人数统计，十字路口行人统计等等方面。(This topic is based on MATLAB skin color statistics system, with the subway car as the actual background, through the prediction method, combined with skin color statistics face to get the number of cars, so as to estimate the degree of congestion, and feedback the results to the station video, so that passengers can know the crowding degree of each car, so as to reasonably allocate passengers in the car, avoid resource waste and congestion GUI interface. It can be applied to classroom statistics, pedestrian statistics at crossroads and so on.)
