In this project, I am going to analyze the profile pictures in two groups in the Wechat, an online chatting platform. People in the first groups are above 25 years old and at work. People in the second group are my friends and are currently studying in CMU. All of them are under 21 and come from different places. Since these two groups of people are so differ in ages, I will analyze the data individually and then compare the result and exam the behaviors.
