Facial recognition and detection is a traditional problem of computer vision, and the problem of facial key points detection is one of the most important branches of it. As the development of deep learning, more and more methods based on it are proposed for solving related issues, which bring numerous revolutionary changes. In our experiment, we propose a simplified method based on Convolution Neural Network for solving the problem of detecting 5 human facial key points. The method mainly consists of 2 sections. The first one is determining the facial area in an image, the output of which is a matrix representing coordinates of the facial area. The second one detects the relative position within the facial area and fine-tune it repeatedly. In the two sections, we design the structure of Neural Network for it, which size of hidden layers is small but stay efficient. We use Caffe, a popular open source framework of deep learning, to build our neural network and get the satisfactory result.
