Embodiment Construction
[0045] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0046] The face alignment method based on coarse-to-fine face shape estimation is a simple but robust face alignment method. Using the coarse-to-fine face shape estimation method based on convolutional neural network can select the face shape with close additional attributes as the initialization shape with high accuracy, thereby reducing the dependence of the initialization shape on the average face and the enhancement algorithm on the face Robustness to differences in head pose, facial expression, occlusion, and lighting conditions improves the performance of the algorithm.
