Good results have been obtained for face alignment in a single image. This is beneficial from use of auxiliary models or prior information. Compared with a single face image, there is much information available in multiple face images of a person. Rigid joint alignment will use the information as a whole. The paper mainly contain two works, i.e. constructing rigid joint alignment of multiple face...
Active Shape Models are a powerful and well known method to perform face alignment. In some applications it is common to have shape information available beforehand, such as previously detected landmarks. Introducing this prior knowledge to the statistical model may result of great advantage but it is challenging to maintain this priors unchanged once the statistical model constraints are applied...
