Patent number: 8099373Abstract: An object detector that includes a number of weak classifiers can be trained using a subset (a “working set”) of training data instead of all of the training data. The working set can be updated so that, for example, it remains representative of the training data. A decision to update the working set may be made based on the false positive sample rate—if that rate falls below a threshold value, an update of the working set can be triggered.Type: GrantFiled: February 14, 2008Date of Patent: January 17, 2012Assignee: Microsoft CorporationInventors: Rong Xiao, Xiao-ou Tang

Patent number: 8014572Abstract: Systems and methods are described for a face annotation framework with partial clustering and interactive labeling. In one implementation, an exemplary system automatically groups some images of a collection of images into clusters, each cluster mainly including images that contain a person's face associated with that cluster. After an initial user-labeling of each cluster with the person's name or other label, in which the user may also delete/label images that do not belong in the cluster, the system iteratively proposes subsequent clusters for the user to label, proposing clusters of images that when labeled, produce a maximum information gain at each iteration and minimize the total number of user interactions for labeling the entire collection of images.Type: GrantFiled: June 8, 2007Date of Patent: September 6, 2011Assignee: Microsoft CorporationInventors: Rong Xiao, Fang Wen, Xiaoou Tang

Patent number: 7949621Abstract: An efficient, effective and at times superior object detection and/or recognition (ODR) function may be built from a set of Bayesian stumps. Bayesian stumps may be constructed for each feature and object class, and the ODR function may be constructed from the subset of Bayesian stumps that minimize Bayesian error for a particular object class. That is, Bayesian error may be utilized as a feature selection measure for the ODR function. Furthermore, Bayesian stumps may be efficiently implemented as lookup tables with entries corresponding to unequal intervals of feature histograms. Interval widths and entry values may be determined so as to minimize Bayesian error, yielding Bayesian stumps that are optimal in this respect.Type: GrantFiled: October 12, 2007Date of Patent: May 24, 2011Assignee: Microsoft CorporationInventors: Rong Xiao, Xiaoou Tang

Patent number: 7590267Abstract: A method and system for detecting faces at different views within images that allocates the computational effort based on a prior probability associated with a view is provided. A face detection system determines whether an image contains a face using detectors that are adapted to detect faces at various views and a filter that filters out windows of the image that are provided to a detector based on a prior probability associated with the view of the detector. Each view has an associated prior probability that a face from a collection of real-life home photographs will be at that view. The face detection system allocates increasing computational effort to a detector as the prior probability of its view increases.Type: GrantFiled: May 31, 2005Date of Patent: September 15, 2009Assignee: Microsoft CorporationInventors: Rong Xiao, Lei Zhang, Yan-Feng Sun, Wei-Ying Ma
