Abstract:
Systems and methods are discussed to localize facial landmarks using a test facial image and a set of training images. The landmarks can be localized on a test facial image using training facial images. A plurality of candidate landmark locations on the test facial image can be determined. A subset of the training facial images with facial features similar to the facial features in the test facial image can be identified. A plurality of shape constraints can be determined for each test facial image in the subset of test facial images. These shape constraints graphically relate to one landmark location from a linear combination of the other landmark locations in the test facial image. Shape constraints can be determined for every landmark within each test facial image. A candidate landmark can be chosen from the plurality of candidate landmarks using the shape constraints.
