  • Patent number: 7499574
    Abstract: The present invention meets these needs by providing temporal coherency to recognition systems. One embodiment of the present invention comprises a manifold recognition module to use a sequence of images for recognition. A manifold training module receives a plurality of training image sequences (e.g. from a video camera), each training image sequence including an individual in a plurality of poses, and establishes relationships between the images of a training image sequence. A probabilistic identity module receives a sequence of recognition images including a target individual for recognition, and identifies the target individual based on the relationship of training images corresponding to the recognition images. An occlusion module masks occluded portions of an individual's face to prevent distorted identifications.

  • Patent number: 7489341
    Abstract: A digital video image stabilization method features scene change detection, adaptive stabilization in two dimensions, prevention of accumulated-compensation saturation, multi-resolution motion estimation, and compatibility with MPEG video encoding standards. The method uses block-based motion estimation on a selected set of macroblocks, which generates and validates a set of motion vectors, to determine how a digital camcorder or other video recording device is moving; accumulates motion data to estimate and preserve overall motion due to panning while eliminating small variations due to shaking; and resets its accumulated motion data when it detects a scene change. The method uses this information to select a sub-image from a larger image for the selected video frame. When one or more edges of the sub-image approach the edges of the larger image, the method reduces its correction factor to transition smoothly to a faster pan and prevent saturation.

  • Patent number: 7463754
    Abstract: A system and a method are disclosed for adaptive probabilistic tracking of an object within a motion video. The method utilizes a time-varying Eigenbasis and dynamic, observation and inference models. The Eigenbasis serves as a model of the target object. The dynamic model represents the motion of the object and defines possible locations of the target based upon previous locations. The observation model provides a measure of the distance of an observation of the object relative to the current Eigenbasis. The inference model predicts the most likely location of the object based upon past and present observations. The method is effective with or without training samples. A computer-based system provides a means for implementing the method. The effectiveness of the system and method are demonstrated through simulation.

  • Patent number: 7450736
    Abstract: Disclosed is a method and system for efficiently and accurately tracking three-dimensional (3D) human motion from a two-dimensional (2D) video sequence, even when self-occlusion, motion blur and large limb movements occur. In an offline learning stage, 3D motion capture data is acquired and a prediction model is generated based on the learned motions. A mixture of factor analyzers acts as local dimensionality reducers. Clusters of factor analyzers formed within a globally coordinated low-dimensional space makes it possible to perform multiple hypothesis tracking based on the distribution modes. In the online tracking stage, 3D tracking is performed without requiring any special equipment, clothing, or markers. Instead, motion is tracked in the dimensionality reduced state based on a monocular video sequence.

  • Patent number: 7430315
    Abstract: The face detection system and method attempts classification of a test image before performing all of the kernel evaluations. Many subimages are not faces and should be relatively easy to identify as such. Thus, the SVM classifier try to discard non-face images using as few kernel evaluations as possible using a cascade SVM classification. In the first stage, a score is computed for the first two support vectors, and the score is compared to a threshold. If the score is below the threshold value, the subimage is classified as not a face. If the score is above the threshold value, the cascade SVM classification function continues to apply more complicated decision rules, each time doubling the number of kernel evaluations, classifying the image as a non-face (and thus terminating the process) as soon as the test image fails to satisfy one of the decision rules.

    Abstract: A duplex automatic document feeder includes first, second, third, and fourth paths, an ejecting path, a scanning module, first and second reversing roller units, a feeding tray, and an ejecting tray. A document is moved from the feeding tray to the scanning module for scanning of a first side surface thereof. Subsequently, the document is moved along a second-side scanning path defined by the first reversing roller unit, the third path, a portion of the first path, the fourth path, and the first reversing roller unit to allow for scanning of a second side surface thereof. After the first and second side surfaces are scanned, the document is moved along a document-inverting path defined by the second reversing roller unit, a portion of the fourth path, the ejecting path, a portion of the second path, the first reversing roller unit, and the ejecting tray.

  • Publication number: 20080137956
    Abstract: Methods and systems are described for three-dimensional pose estimation. A training module determines a mapping function between a training image sequence and pose representations of a subject in the training image sequence. The training image sequence is represented by a set of appearance and motion patches. A set of filters are applied to the appearance and motion patches to extract features of the training images. Based on the extracted features, the training module learns a multidimensional mapping function that maps the motion and appearance patches to the pose representations of the subject. A testing module outputs a fast human pose estimation by applying the learned mapping function to a test image sequence.

  • Patent number: 7379602
    Abstract: A method for representing images for pattern classification extends the conventional Isomap method with Fisher Linear Discriminant (FLD) or Kernel Fisher Linear Discriminant (KFLD) for classification. The extended Isomap method estimates the geodesic distance of data points corresponding to images for pattern classification, and uses pairwise geodesic distances as feature vectors. The method applies FLD to the feature vectors to find an optimal projection direction to maximize the distances between cluster centers of the feature vectors. The method may apply KFLD to the feature vectors instead of FLD.

  • Patent number: 7369682
    Abstract: A system and a method are disclosed for an adaptive discriminative generative model with a probabilistic interpretation. As applied to visual tracking, the discriminative generative model separates the target object from the background more accurately and efficiently than conventional methods. A computationally efficient algorithm constantly updates the discriminative model over time. The discriminative generative model adapts to accommodate dynamic appearance variations of the target and background. Experiments show that the discriminative generative model effectively tracks target objects undergoing large pose and lighting changes.

  • Publication number: 20080067736
    Abstract: An automatic document feeder includes first, second, third, and fourth paths for guiding movement of a document. The document is fed through the first path and a scanning module so as to allow for scanning of a first side surface of the document. Thereafter, a switching gate is pivoted to a first position so as to allow the document to be moved from a front section of the second path onto a roller unit via the fourth path and a rear section of the third path. The rotational direction of the middle roller is changed in response to movement of the document onto the roller unit so as to allow the document to be moved onto the first path via the third path, thereby allowing for a subsequent scanning operation on a second side surface of the document. The automatic document feeder further includes a document-inverting path such that documents are automatically arranged according to paper number.
