FACE ALIGNMENT WITH SHAPE REGRESSION

摘要

The subject matter described herein relates to face alignment via shape regression. A method, computer storage medium, and system are provided. In one embodiment, the method comprises receiving an image including a face; and performing shape regression to estimate a facial shape in the image. For each stage in the shape regression, a local feature is extracted from a local region around each facial landmark in the image independently; and a joint projection is performed based on local features of multiple facial landmarks to predict a facial shape increment. Then, a facial shape of a current stage is generated based on the predicted facial shape increment and a facial shape of a previous stage.

主权项

1. A method for face alignment implemented at least in part by a computer comprising:
receiving an image including a face; and estimating, by a processor, a facial shape in the image with shape regression, wherein the facial shape is represented by a multiple of facial landmarks, the estimating including, for each stage in the shape regression,
extracting a local feature from a local region around each facial landmark in the image independently;organizing two or more of the local features based on correlations among the facial landmarks to predict a facial shape increment; andgenerating a facial shape of a current stage based on the predicted facial shape increment and a facial shape of a previous stage.
