Recently, smartphone and any other smart devices are used by many people, Beyond the base function of telephone, smartphone does so many functions and tasks for humans. Fundamental technics are object detections by smartphone camera. In this project, I’ll use the face detection and finger detection in android devices for using human detection and comparison. First, independent face detection algorithm will be used in android device and then by using finger detection algorithm, smartphone device can catch the human face(pointing human face). Then analyze the human face by comparing the human face database(machine learning algorithm will be used). So, in this project I would find the optimal resource factor used of between three procedures(face detection, finger detection, and human face analysis) If these technologies are used properly, smartphone users could detect the suspicious or specific people individually. Also, if these technologies are developed more perfectly, I think many polices or soldiers do their works well economically by using their smart devices(including wearable devices)
