摘要： The present invention is a method and system to provide correspondences between a face camera track and a behavior camera track, for the purpose of making correspondence between the data obtained from each track. First, multiple learning machines are trained so that each of the machines processes pairwise person images from a specific pose region, and estimates the likelihood of two person images belonging to the same person based on image appearances. Then, the system acquires a person image associated with a behavior camera track, determines the pose of the person image based on its floor position, and corrects the pose of the person image. The system also acquires person images from face camera images associated with a face camera track, and combines the images with corrected person images from the previous step to form pairwise person images. The pairwise person image is fed to the trained pose-dependent pairwise person verification machines according to the pose of the person images, to compute the appearance match scores between the pair of person images. Finally, the combination of the appearance match scores and the spatiotemporal match scores of the pair of person images determines whether or not the person images belong to the same person.

摘要： The present invention is a method and system to provide a face-based automatic gender recognition system that utilizes localized facial features and hairstyles of humans. Given a human face detected from a face detector, it is accurately localized to facilitate the facial/hair feature detection and localization. Facial features are more finely localized using the geometrically distributed learning machines. Then the position, size, and appearance information of the facial features are extracted. The facial feature localization essentially decouples geometric and appearance information about facial features, so that a more explicit comparison can be made at the recognition stage. The hairstyle features that possess useful gender information are also extracted based on the hair region segmented, using the color discriminant analysis and the estimated geometry of the face. The gender-sensitive feature vector, made up from the extracted facial and hairstyle features, is fed to the gender recognition machines that have been trained using the same kind of gender-sensitive feature vectors of gallery images.

摘要： The present invention is a method and system to estimate the visual target that people are looking, based on automatic image measurements. The system utilizes image measurements from both face-view cameras and top-down view cameras. The cameras are calibrated with respect to the site and the visual target, so that the gaze target is determined from the estimated position and gaze direction of a person. Face detection and two-dimensional pose estimation locate and normalize the face of the person so that the eyes can be accurately localized and the three-dimensional facial pose can be estimated. The eye gaze is estimated based on either the positions of localized eyes and irises or on the eye image itself, depending on the quality of the image. The gaze direction is estimated from the eye gaze measurement in the context of the three-dimensional facial pose. From the top-down view the body of the person is detected and tracked, so that the position of the head is estimated using a body blob model that depends on the body position in the view. The gaze target is determined based on the estimated gaze direction, estimated head pose, and the camera calibration. The gaze target estimation can provide a gaze trajectory of the person or a collective gaze map from many instances of gaze.

摘要： The present invention is a method and system for measuring human emotional response to visual stimulus, based on the person's facial expressions. Given a detected and tracked human face, it is accurately localized so that the facial features are correctly identified and localized. Face and facial features are localized using the geometrically specialized learning machines. Then the emotion-sensitive features, such as the shapes of the facial features or facial wrinkles, are extracted. The facial muscle actions are estimated using a learning machine trained on the emotion-sensitive features. The instantaneous facial muscle actions are projected to a point in affect space, using the relation between the facial muscle actions and the affective state (arousal, valence, and stance). The series of estimated emotional changes renders a trajectory in affect space, which is further analyzed in relation to the temporal changes in visual stimulus, to determine the response.

摘要： The present invention is a method and system for rating in-store media elements based on the measurement for behavior patterns and demographics of the audience in the vicinity of the media element, where a plurality of input images of the audience are captured by at least a means for capturing images in the vicinity of the media element. The input images are processed by automated video analytic algorithms in order to measure the behavior patterns and demographics of each person in the audience tied to the media element. The measurements for the behavior patterns and demographics of the audience from the target media elements are aggregated. A set of ratings for the media element is calculated based on the measurements. The measured media elements are sampled, and the audience measurement for the sample is extrapolated to other media elements for in-store locations or for a group of stores. The ratings are converted into a standardized output. The standardized output facilitates comparisons among a plurality of media elements. The rating can be used to plan media types in the media element for reaching targeted demographics.

摘要： The present invention is a method and system for automatically recognizing which products a shopper intends to find or purchase based on the shopper's trajectory in a retail aisle. First, the system detects and tracks the person to generate the trajectory of the shopper. Then some of the dynamic features are extracted from the shopper trajectory. The shopper trajectory features of a given trajectory are typically the positions, the motion orientations, and speeds at each point of the trajectory. A shopper behavior model is designed based on some of the primitive actions of shoppers. The last step of the method is to analyze a given shopper trajectory to estimate the shopper's intention. The step either utilizes decision rules based on the extracted shopper trajectory features, or utilizes a trained Hidden Markov Model, to estimate the progression of the primitive actions from the trajectory. The decoded progression of the shopper behavior states is then interpreted to finally determine the shopper's intention.

摘要： The present invention is a method and system for selecting and storing videos by applying semantically-meaningful selection criteria to the track sequences of the trips made by people in an area covered by overlapping multiple cameras. The present invention captures video streams of the people in the area by multiple cameras and tracks the people in each of the video streams, producing track sequences in each video stream. The present invention determines a first set of video segments that contains the trip information of the people, and compacts each of the video streams by removing a second set of video segments that do not contain the trip information of the people from each of the video streams. The present invention selects video segments from the first set of video segments based on predefined selection criteria for the statistical behavior analysis. The stored video data is an efficient compact format of video segments that contain the track sequences of the people and selected according to semantically-meaningful and domain-specific selection criteria. The final storage format of the videos is a trip-centered format, which sequences videos from across multiple cameras, and it can be used to facilitate multiple applications dealing with behavior analysis in a specific domain.

摘要： The present invention is a system and method for determining the hierarchical purchase decision process of consumers in front of a product category. The decision path of consumers is obtained by combining behavior data with the category layout and transaction data based on observed actual in-store purchase behavior using a set of video cameras and software for extracting sequence and timing of each consumer's decision process. A hierarchical decision tree structure comprises nodes and edges, wherein a node represents the state-of-mind of the consumer, the number of nodes is predefined, and an edge represents the transition of the decision. The decisions for each product group are captured down to the product attribute level and analyzed by demographic group. The outcome provides relative importance of each product attribute in the purchase decision process, and helps retailers and manufacturers to evaluate the layout of the category and customize it for key segment.
