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.Type: GrantFiled: October 23, 2014Date of Patent: July 10, 2018Assignee: Microsoft Technology Licensing, LLCInventors: Xudong Cao, Yichen Wei, Jian Sun, Shaoqing Ren

Publication number: 20140341443Abstract: This disclosure describes a system for jointly modeling images for use in performing facial recognition. A facial recognition system may jointly model a first image and a second image using a face prior to generate a joint distribution. Conditional joint probabilities are determined based on the joint distribution. A log likelihood ratio of the first image and the second image are calculated based on the conditional joint probabilities and the subject of the first image and the second image are verified as the same person or as different people based on results of the log likelihood ratio.Type: ApplicationFiled: May 16, 2013Publication date: November 20, 2014Applicant: MICROSOFT CORPORATIONInventors: Xudong Cao, Fang Wen, Jian Sun, Dong Chen

Publication number: 20140185924Abstract: A two-level boosted regression function is learned using shape-indexed image features and correlation-based feature selection. The regression function is learned by explicitly minimizing the alignment errors over the training data. Image features are indexed based on a previous shape estimate, and features are selected based on correlation to a random projection. The learned regression function enforces non-parametric shape constraint.Type: ApplicationFiled: December 27, 2012Publication date: July 3, 2014Applicant: MICROSOFT CORPORATIONInventors: Xudong Cao, Yichen Wei, Fang Wen, Jian Sun
